delivered the opinion of the Court.
This is a Workmen’s Compensation case in which the petitioning employee is seeking to recover benefits under *362 the Act for a ruptured appendix and the disabilities resulting therefrom. The Trial Judge found that the employee’s injuries arose out of his employment and allowed a recovery.
The employer and his insurance carrier have seasonably appealed and assigned error on several grounds. The controlling issue, however, is whether or not there is any material evidence to sustain the finding of the Trial Judge that the ruptured appendix and the disabilities resulting therefrom arose out of the employment of the petitioning employee within the meaning of Section 6852(d) of the Supplement to the Code of Tennessee (1950).
The employee, Foster P. Friddell, is a carpenter who was employed by his father Shirley L. Friddell. On February 19, 1954, the employee, while in the course of his employment, fell from a scaffold some six to eight feet to the ground. In so doing he injured his hand and his ankle. There is no question but that, these injuries were compensable under the Act. He testified that he fell upon his stomach or side. He was immediately taken to a Dr. Hair who treated his hand and his ankle. The Doctor testified that Friddell did not complain to him at that time of any pain in his stomach or abdomen. Frid-dell, however, testified that shortly after the accident he became sick at his stomach, but that he associated this sickness with the pain he suffered from his ankle.
Friddell continued to be sick at his stomach, so much so that though he attempted to return to work he was unable to do so. About three or four days after the accident he told Dr. Hair of his sickness, and the Doctor told him “to take something for it,” and to come back to see him. The sickness continued, growing progressivély worse. Some six days after the accident Friddell went to a Dr. *363 Landham, who after examining Friddell called in a surgeon, a Dr. Patterson. Friddell was placed in the hospital, where he stayed some 11 or 12 days. Friddell’s abdomen was very rigid, distended and tender, his blood count was high and he had a small mass in the right lower quadrant of his abdomen. Both Doctors Landham and Patterson thought he probably had suffered a hemorrhage in the muscles of his abdomen. He was given antibiotics and his condition improved somewhat, but the mass remained, as did the soreness. It was then decided to operate on Friddell; and on May 4, 1954, an operation was performed. It was then found the Friddell had a ruptured appendix, which by natural processes had been “ walled off, anteriorly, next to the wall of the abdomen. ’ ’ At the time of the trial he still had some tenderness in that region of his abdomen, and Dr. Landham testified, that Friddell had approximately a 10'% disability at the time of the trial.
Cases such as this involving the causal connection between an accidental injury and a disease or physical disability not commonly associated with a traumatic origin are troublesome and difficult; but that difficulty is made somewhat simpler for this Court by virtue of the well settled'rules governing the scope and nature of its functions in reviewing Workmen’s Compensation cases.
The Workmen’s Compensation Act must be liberally construed, Tennessee Code Section 6901, and any reasonable doubt as to whether an injury arose out of the employment within the meaning of the Act must be resolved in favor of the employee.

v.
Tapp,
This Court, in reviewing such cases, does not reweigh the evidence, but searches the record only so far as is necessary to determine whether or not there is
*364
material evidence to support the finding of the Trial
Jndg’e;
and the weight of the evidence and the credibility of the witnesses are finally determined in the Trial Conrt.

v.
Musgrave,
Dr. Landham was asked:
“RD1 Doctor, one question. In your opinion what happened in this case? You’ve treated this man from a few days after this accident until now. What is, in your opinion, did this trauma cause an aggravation of a preexisting condition which caused this man’s appendix to rupture ? ’ ’
He answered:
“I think that’s what happened in the case. I— I— really do, giving the man the benefit of the doubt. In other words, I cannot say absolutely that this is black and this is white, but—
“RD2 Doctor — •
“A. — I do believe that this man received a blow which evidently must have aggravated a pre-existing condition, because from the time that he fell off of that scaffold up until the time he came into my office, he complained moré and more of the same type of pain, getting worse all along.”
The employee, Friddell, testified that he did hit his abdomen in falling from the scaffold, and that shortly thereafter he became sick at his stomach. He is substantiated in this by his brother, another employee, who saw the accident.
Dr. Patterson testified that a fecalith, “kind of a little hard marble,” was found when the operation was performed and that it was conceivable that a fall could have done something to this fecalith and caused it to block the *365 base of tbe appendix and tbns conld have cansed tbe resulting rnptnre.
There was testimony that it was exceedingly improbable that a rnptnred appendix would have a traumatic origin; but tbe Trial Judge chose to credit tbe testimony that Friddell did sustain an injury to bis abdomen when he fell, that be shortly thereafter became sick at bis stomach, and that there was a causal connection between tbe fall and tbe ruptured appendix. There is material evidence to support bis finding.
Tbe plaintiffs in error charge that there was no direct and positive testimony, that tbe fall actually caused tbe ruptured appendix; but absolute certainty is not required to support an award in this State.
Powers
v.
Beasley,
Tbe fact that it may be unusual for a ruptured appendix to bave a traumatic origin, or even that such a result is exceedingly improbable, does not require a bolding that tbe trauma did not in a particular case bave such a result. If, as here, there is material evidence of a causal connection between tbe injury or accident and tbe resulting disease or disability, no more is required. Benjamin F. Shaw Co. v. Musgrave, supra.
Plaintiffs in error bave cited several cases from other jurisdictions wherein it has been held that there was no causal connection between a ruptured appendix or appendicitis and tbe employment of tbe petitioning employee.

v.
Department of Labor,
26 Wash. (2d) 233,
The plaintiffs-in-error have also assigned error upon the ground that “the Court found that the injury resulted in an aggravation of a previously existing condition which was not alleged in petitioner’s pleadings, and defendants had no notice that proof of same would be introduced. ’ ’ The petition, however, alleged that the petitioner “suffered an internal rupture in the lower quadrant of his abdomen.” Such an allegation is sufficient fairly to raise the issue of the aggravation of a preexisting condition, in view of the elementary rules of pleading in Workmen’s Compensation cases.
Rhyne
v.
Lunsford,
All assignments of error are overruled. The judgment of the Trial Court is affirmed, with costs adjudged against the appellants Shirley L. Friddell and the Great American Indemnity Company.
