The Seattle Seahawks violated the league concussion protocol during Thursday night game against the Arizona Cardinals after they allowed quarterback Russell Wilson to re-enter the game before going to the locker room and being cleared by the appropriate medical personnel, reports ESPN.com's Adam Schefter.
The team can be fined up to $150,000 according to the league's rules.
In the third quarter of Seattle's 22–16 victory, Wilson was hit on the chin by Cardinals linebacker Karlos Dansby. Before the next play was snapped, referee Walt Anderson ordered Wilson to go to the sideline so he could checked out by the medical staff.
