Bryant, who left Sunday night's season-ending loss to the Washington Redskins in the fourth quarter, needed help to his locker and to the shower area after the game. He left FedEx Field in a wheelchair and was moved from coach to first class on the flight home from Washington, D.C., because the team's medical staff was trying to find a comfortable way to lay him down.
Bryant then was helped off the team plane early Monday morning and went to the hospital thereafter. He was seen walking out of the trainer's room using crutches Monday afternoon.
Bryant declined to comment.
"It completely locked up on him after the game," Cowboys coach Jason Garrett said of Bryant's back. "He couldn't, literally people had to help him get his clothes on after the game, carry him to the bus and we put him up in first class on the plane so he could have a little space and some comfort."
Bryant was tested for possible structural damage in his back. Garrett said the team was awaiting the results of those tests.
"We think ultimately it's going to get under control," Garrett said. "It's a pretty significant injury, and he obviously couldn't come back and play and really couldn't walk until this morning."
Bryant suffered the injury while running down the field with a little more than nine minutes to play in Sunday's game. He had four catches for 71 yards against the Redskins and his streak of seven consecutive games with at least one touchdown ended.
Bryant also is playing with a fractured left index finger that will require surgery at a date yet to be determined.
