Utah running back Zack Moss' knee injury was the result of a pre-existing condition that was triggered when the junior climbed into bed, according to coach Kyle Whittingham.
Whittingham called the injury "very strange" while discussing it with reporters after Utah's 32-25 win over Oregon on Saturday. The coach said Moss' knee "locked up on him" when he was getting into bed.
"It could have been a week ago, a month ago, a year ago," Whittingham told reporters of Moss' original injury. "There's just no way to tell."
Previous reports had indicated that Moss suffered the injury during practice Wednesday.
