David Ross appeals the district court’s denial of his motion for summary judgment on his defense of qualified immunity. We reverse.
I.
Appellee Christopher Prosser is an inmate at the Jefferson City Correctional Center who sustained permanent injuries when inmate Charles Pilgrim attacked him. Prosser and Pilgrim were housed in adjoining cells in Housing Unit 3-A. A few days prior to the incident, a disturbance (characterized by both parties as a “small-scale riot”) occurred in the prison recreation yard. Because of the riot, prison officials placed Unit 3-A in “lock-down,” that is, prisoners were forced to remain in their cells twenty-four hours a day. On the day that Prosser was injured, the prison officials partially lifted the lock-down to allow the inmates to eat in the cafeteria. When Prosser stepped out of his cell to file into the lunch line, Pilgrim hit him over the head with what witnesses described as a metal can concealed in a sock or towel. Prosser fell to the ground, and Pilgrim began to kick him in the stomach, chest, and face. The attack ended when several guards forcibly intervened.
When the attack began, Ross was stationed as a prison guard in Unit 3-A. The evidence is uncontroverted that he was standing alone at the end of the walkway, near Prosser’s and Pilgrim’s cells. More than a dozen prisoners stood between him and the other prison guards at the far end of the walkway. When Pilgrim hit Prosser, Ross did not intervene; instead, he ran to the other end of the walkway to seek help. A short while later, several guards arrived and pulled Pilgrim off Prosser, and Prosser was rushed to the hospital.
Prosser filed this action under 42 U.S.C. § 1983 against Ross, claiming that Ross violated his Eighth Amendment right to be free from cruel and unusual punishment. He maintains that Ross acted unconstitutionally by failing to prevent Pilgrim’s attack, by allowing Pilgrim to “lie in wait” outside his cell, by failing to intervene immediately to stop the attack, and by waiting too long to seek assistance from other guards. (Prosser also offered evidence that Ross attempted to hire another inmate to kill him after he filed this lawsuit. We believe that this evidence, besides being inherently improbable, is not probative on the question of Ross’s animus at the time of Pilgrim’s attack, even if that animus itself were somehow relevant to Pros-ser’s claims.) The district court denied Ross’s motion for summary judgment on his qualified immunity defense because it found that “material factual disputes on plaintiffs claims against defendant Ross” precluded it. The district court did not indicate in its order what material facts it believed were in dispute.
II.
We must first determine whether this appeal is properly before us. Although some orders denying qualified immunity are ap-pealable before trial,
Mitchell v. Forsyth,
III.
Ross is entitled to qualified immunity unless he violated Prosser’s “clearly established” constitutional rights.
Harlow v. Fitzgerald,
The Supreme Court has made it clear that the Eighth Amendment encompasses an inmate's right to be protected from harm by fellow inmates.
Farmer v. Brennan,
— U.S. -, -,
Taken together, the cases indicate that Ross is entitled to qualified immunity unless a reasonable official would have known that Ross’s actions constituted a deliberate, callous, or reckless disregard for Prosser’s safety. With this principle in mind, we review each of Prosser’s allegations in turn.
A.
Prosser alleges first that Ross unconstitutionally failed to prevent Pilgrim’s attack. We find in the record no evidence whatsoever to support this allegation. Prosser himself admitted in his deposition that the attack took him by surprise. There was no evidence that the two inmates harbored any hostile feelings toward one another; indeed, the two had never had so much as a disagreement.
We have held that prison officials are entitled to qualified immunity from claims arising out of a surprise attack by one inmate on another.
See Falls v. Nesbitt,
B.
Prosser also alleges that Ross allowed Pilgrim to “lie in wait” outside his cell and attack him as he exited. The record is again devoid of evidence that Ross behaved recklessly. In his deposition, Prosser speculated that because he was attacked immediately upon exiting his cell, Pilgrim must have been standing outside the cell when the doors opened. He further speculated that Ross recklessly allowed Pilgrim to move against the flow of the lunch line and stand next to his cell door.
We regard all of Prosser’s assertions as purely conjectural.
Miller v. Solem,
C.
Prosser’s third claim is that Ross violated his Eighth Amendment rights by failing to intervene in the attack. Prosser asserts that the situation posed no danger to Ross and that therefore the decision not to intervene violated his clearly established rights. But we have held that prison guards have no constitutional duty to intervene in the armed assault of one inmate upon another when intervention would place the guards in danger of physical harm.
Arnold v. Jones,
The fact that inmate witnesses testified that Ross was not in danger cannot change these facts. These assertions, again, are merely conjectural.
See Miller v. Solem,
D.
Finally, Prosser claims that Ross waited an excessive amount of time before he sought help. Prosser’s only support for this claim is inmate Dennis Blackman’s deposition testimony that Ross waited at the end of the walkway for thirty seconds after the attack began. Prosser argues that this testimony creates a genuine issue of fact on the question of whether Ross recklessly disregarded his safety. We disagree.
The difficulty with Blackman’s testimony is that it contradicts Prosser’s own characterization of the events. In his initial complaint, Prosser alleged that Ross ran away as soon as Pilgrim began to attack him, and it was only in the context of his response to Ross’s summary judgment motion that Prosser claimed that Ross waited too long before seeking help. Prosser repeated his original description of the events in his deposition, testifying that “he [Pilgrim] only hit me one time before Ross ran.” We have held that a party cannot avoid summary judgment by contradicting his own earlier testimony.
Wilson v. Westinghouse Elec. Corp.,
Our conclusion that Blackman’s testimony cannot raise a material issue of fact is strengthened by the fact that Blackman’s testimony is itself fraught with contradictions. Blackman initially testified that Ross sought help immediately:
Q: Okay. And what happened immediately after that?
A: I stepped out. I saw the tall guy swing and hit Mr. Prosser, and I looked up, and I was — I see him go down, and I looked up, because I saw somebody just kind of moving past me, and I looked by, and it was like, you know, saw a brown uniform and saw it was Ross.
Then, when he was asked how much time elapsed before Ross ran past him Blackman replied, “about thirty seconds, I’d say.” On
*1009
cross-examination, Blackman again changed his testimony, indicating that less than thirty seconds elapsed. Later yet, at Prosser’s urging, Blackman indicated “it was a long time” before Ross sought assistance. We are mindful of our obligation to credit all of the evidence that favors the nonmovant,
see, e.g., Anderson v. Liberty Lobby,
Summary judgment is proper unless “the evidence, viewed in the light most favorable to [Prosser], is such that a reasonable jury could return a verdict in his favor.”
Foster v. Metropolitan Airports Comm’n,
IV.
We conclude that a reasonable official in Ross’s position at the time the attack occurred would not have believed that his actions violated Prosser’s clearly established constitutional rights. Ross is therefore entitled to qualified immunity as a matter of law.
