Bryant came to the sideline and tried to stretch the leg before limping off the field. He was checked by trainers and did not return to practice.

Several media members, including the beat reporter for the Cowboys’ website, tweeted video of Bryant’s injury.

Bryant later tried to calm Cowboys fans by telling them he’ll be fine.
