Most teams do that. Like I said earlier in the thread, Maurkice Pouncey was carted off the field with a clear leg injury, remained in the locker room, came back out on crutches hobbling around and his return was "questionable." I don't know why teams do it, but most of the time I've seen them as questionable – even with concussions where it's obvious the player's done for the day. That's what I said earlier in the thread. I'd say 75% of the time when an injury occurs, the sideline report says that the player's return is questionable, no matter the severity of the injury.
