In the first quarter of Sunday's Bears-Lions game, Detroit cornerback Rashean Mathis appeared to have suffered a concussion while trying to make a tackle on Bears running back Matt Forte.
Mathis was checked out by both medical staffs following the hit, then walked off the field under his own power.
He underwent two tests, one on the sidelines and another at halftime, and said he passed both of them.
But Bears doctors overruled Detroit's decision to allow Mathis to return to the game believing the cornerback briefly lost consciousness. Here's a clip of Mathis being checked out on the sidelines by Detroit's doctors:
"I ran out on the sideline because I took another test at halftime. They're like, 'You're good,'" Mathis said after the Lions' 40-32 win. "So I ran down the steps, thought I was cleared to play -- but then our head guy said their doctor said, 'You might have went out for a second and protocol says you can't go.'"
Mathis believes he didn't lose consciousness and was frustrated he couldn't return, but their victory helped ease away his feelings.
Asked if Bears doctors possibly held Mathis out for Chicago's sake, he responded, "that's not my job to get into that."
