OPINION
A jury found for appellant in this worker’s compensation case, but it also found that 90% of her total and permanent disability was due to three prior work-related injuries. Consequently, the trial court awarded judgment for 10% of damages appellant would have otherwise received.
The main question presented is whether the jury findings that prior injuries contributed 90% of appellant’s disability can be upheld without expert testimony to establish at least a reasonable percentage range within which the prior injury contributed to the disability. We hold that expert testimony fixing a percentage range by which prior injuries contributed to the disability is required to support a reduction of benefits under article 8306, section 12c. Because there was no such evidence in this case, we hold the jury finding on contribution of prior injuries should have been disregarded. Consequently, we reverse and render judgment for appellant for full benefits.
Margaret Wilson worked as a cook for appellee, Klein Independent School District. She twisted her back on October 22, 1985, while working at Doerr Intermediate School, and could no longer work. That injury is the basis for this award.
After the last injury, Wilson’s doctor diagnosed her condition as arachnoiditis, scar tissue around nerves in the spinal column. He testified this condition was usually found in post-operative patients and surgery would worsen the scarring. The prognosis was permanent or long-term incapacity. He testified she could not work due to the incapacity, which was “triggered” by the October 22, 1985 injury. That was “the straw that broke the camel’s back,” he stated, which “probably ... triggered arachnoiditis.” The doctor said Wilson could not pass a pre-employment physical.
At trial, Wilson denied injuries other than those of January 24,1984 and October 22, 1985, but this was impeached by her medical records. They showed she had been in pain since the January 1984 injury and mentioned previous injuries and possible arachnoiditis before October 22, 1985. Three doctors examined myelograms of appellant’s back taken before and after October 22, 1985. Dr. Norton found “the sub-arachnoid sac from the L4-5 level ... totally unchanged in appearance in comparison to the exam of 2-13-84.” Dr. Walters concluded the myelograms “revealed the same arachnoiditis changes that were noted before.” Dr. Wendenberg concluded the second myelogram showed the same appearance as the first.
Wilson’s supervisor testified she was an average worker until October 22, 1985. She saw Wilson’s knee buckle and saw her try to catch herself with her other knee when she fell. Appellee’s Food Service Director testified she would not hire anyone in Wilson’s post-October 22,1985 condition.
Appellee’s pleadings contended Wilson’s prior injuries either contributed to or solely caused her incapacity. A jury question, submitted over Wilson’s objection, asked whether “the prior injuries, if any, contributed to the present incapacity and, if so, the percentages of incapacity contributed by each....” The jury found:
(1) the injury of October 22, 1985, was in the course and scope of employment and caused total and permanent incapacity beginning that day;
(2) the injuries at work of February 7, 1983, January 24, 1984, and May 29, 1985, contributed 10%, 60%, and 20%, respectively, to the incapacity, a total of 90%.1
The trial court awarded Wilson 10% of total and permanent disability benefits, in accordance with the jury findings.
Wilson’s first three points of error contend the evidence is legally and factually
In reviewing legal sufficiency points, we consider only the evidence and inferences supporting the finding, viewed in the most favorable light, and disregard all conflicting evidence. Garza v. Alviar,
Wilson had to prove 1) an injury, 2) while in the course of employment, and 3) the extent and duration of the injury. Texas Employers’ Ins. Ass’n v. Page,
(a) If an employee who has suffered a previous injury shall suffer a subsequent injury which results in a condition of incapacity to which both injuries or their effects have contributed, the association shall be liable because of such injury only for the compensation to which the subsequent injury would have entitled the injured employee had there been no previous injury; ...
Therefore, when a prior compensa-ble injury contributes to a subsequent injury, the insurer owes compensation only for the percentage of incapacity caused by the “new” injury. Hines v. Aetna Casualty & Sur. Co.,
Section 12c is an apportionment scheme that abolished the “full responsibility” rule whereby an insurer was liable for the entire disability, even that caused by a preexisting disability. Liberty Mut. Ins. Co. v. Peoples,
Appellee contends that appellant did not suffer an injury causing any incapacity on October 22, 1985 because the myelograms showed the same back condition before and after the accident. Appellee contends this evidence supports the verdict because the jury could have inferred that appellant’s condition was 90% (or wholly) caused by prior injuries. We disagree. The issue is not whether appellant’s myelogram changed. It is whether her ability to work changed. It is undisputed that before October 22, 1985 appellant was an average worker. After that date, she could neither work nor pass an employment physical. Appellee relies exclusively on Lumbermen’s Mutual Casualty Company v. Martinez,
The contribution of prior or subsequent injuries to the claimant’s present incapacity is an affirmative defense. In order to reduce the worker’s recovery under sections 12c, the insurer must prove (1) the prior injury was compensable; (2) it contributed to the present disability; and (3) the amount or percentage of such contribution. Transport Ins. Co. v. Mabra,
The supreme court in Mabra did not state how the insurer’s burden of proof on percentages could be carried. Texas intermediate appellate courts, including this one, have repeatedly held that evidence similar to that in this case constituted no evidence of the amount or percentage of contribution required in Mabra. A strikingly similar case is Transamerica Insurance Co. of Texas v. Hernandez,
In order to reduce appellee’s recovery because of a prior injury, appellant had to prove also the amount or percentage of such contribution. Charter Oak Fire Ins. Co. v. Barrett,655 S.W.2d 333 , 337 (Tex.App. — San Antonio 1983, no writ). An expert need not testify to the exact percentage of the disability attributed to the prior injury by the jury, as long as he provides the jury with a reasonable percentage range within which that injury contributed to the disability. See Harrison v. Texas Employers Ass’n,747 S.W.2d 494 , 497 (Tex.App. — Beaumont 1988, writ denied).

Since there is no testimony even of a range of percentages on which the jury could have based its finding of a 90% contribution, the trial court correctly disregarded the jury’s findings on contribution of a prior injury.
Id. at 611-12.
In Hartford Accident & Indem. Co. v. Contreras,
We do not consider that there is any evidence on the amount or percentage contributed to the plaintiff’s incapacity at the time of trial by the subsequent injury.
Id. at 428.
Other courts have made similar holdings. Texas Employer’s Ins. Ass’n v. Gomez,
Two recent cases found evidence justified a reduction due to a prior injury where
Finally, in Lumbermen’s Mutual Casualty Co. v. Martinez,
The Martinez opinion states:
Contreras, Monroe, Barrett, and Gomez3 do not hold that there must be medical opinion testimony to support the finding of the amount of contribution. In those cases, it appears that there was a complete absence of evidence, medical and nonmedical, to support a finding or submission of an issue on the amount of contribution.
Id. at 623.
We disagree with this description of Contreras and Gomez. In both cases, physicians gave evidence that the injury was a “reinjury” and “the result of an old injury.” Contreras,
We hold that there is legally and factually insufficient evidence to support the jury findings in question 10 as to specific percentages of contribution to Wilson’s incapacity; therefore, the trial court erred in denying her motions to disregard question 10 and for new trial.
Points of error one, two, and three are sustained.
The fourth and fifth points of error contend that because the evidence is legally and factually insufficient to support the percentage findings in question number 10, we should disregard the jury’s finding in
Points of error four and five are sustained.
In points of error six and eight, Wilson contends the evidence is legally and factually insufficient to support the deemed finding under questions nine and ten that the prior injury of February 7, 1983, was a compensable injury. We need not reach these points of error because of our decision to sustain points of error one through five. We note, however, that Wilson testified she was hurt at work on that date and was “off for a week.” This constitutes evidence of a compensable injury. TEIA v. Dryden,
In her seventh and ninth points of error, Wilson contends the evidence is legally and factually insufficient to support the deemed finding under questions nine and ten that her prior injury of May 29, 1985, was a compensable injury. We need not reach these points because of our decision on points one through five. We note, however, that appellee’s exhibit four was a compensation claim form signed by Wilson on July 12,1985, claiming an injury at work on May 29, 1985, for which she began losing time on May 31, 1985, and stating she had not returned to work as of July 12, 1985. This constitutes probative evidence of a compensable injury, and there is no evidence to the contrary.
The tenth point of error contends the trial court erred in not awarding prejudgment interest of 4%, as allowed by Tex.Rev. Civ.Stat.Ann. art. 8306a (Vernon 1967)
Point of error 10 is sustained.
Appellee brings two cross-points of error. In cross-point one, it contends there is no evidence or insufficient evidence to support the jury’s answer that appellant sustained an injury causing incapacity on October 22, 1985.
Appellee has not directed us to a place in the record where these contentions were preserved. Tex.R.App.P. 74(d), (f). Salinas v. Fort Worth Cab & Baggage Co., Inc.,
Cross-point of error one is overruled.
In cross-point two, appellee contends the judgment should be reformed to terminate postjudgment interest after the date it tendered payment of the judgment, June 1, 1989. In light of our decision to reverse the judgment, this contention is moot. Moreover, appellee has not pointed out that it requested and was denied such relief in the trial court. Tex.R.App.P. 52(a); 74(d), (f). Cross-point two is overruled.
The judgment of the trial court is reversed, and judgment is rendered that appellant receive total and permanent benefits and appropriate prejudgment interest. We will render judgment for that amount if the parties can agree on the amount within
