Bryant thought he was healthy enough to participate, but heeded the orders of Cowboys' trainer Jim Maurer.
"I go to Jim and it's his job and he wanted me to sit out today and I was just following orders," Bryant said. "It's real tough for me, because I love competing and love the game of football. I just feel like with moments like this, you just got to follow orders."
Today would have been the first day that both Bryant and Patrick Crayton took the field together with Crayton returning to the team after a brief holdout.
This, of course, isn't Bryant's first injury, so it's good to see that the Cowboys are being cautious with his health - especially during the offseason.
Bryant, the Cowboys' 2010 first-round draft pick, hasn't played in a game since Sept. 19, when he was suspended by the NCAA for lying to investigators about his relationship with Deion Sanders. His time away from the field raised some questions about his conditioning, and he was so winded in his very first Cowboys practice that he missed a few reps.
He missed his third practice after tweaking his ankle and missed another because of food poisoning. He also has had a sore hip, though it was not considered serious.
Cowboys head coach Wade Phillips expects Bryant to be available for the final day of OTAs on Thursday.
