Recently retired Matt Birk will replace Art Shell as one of two appeals officers approved by the NFL and the players' union.
Birk, who played center on the Super Bowl-winning Baltimore Ravens this year before ending his 15-year career, will join Ted Cottrell in the job.
Both the league and the NFL Players Association must approve each officer, and the union's executive committee asked for Birk to take over for Shell. The league has agreed to that move, and both sides approved Cottrell to remain in the position.
Under the collective bargaining agreement signed in 2011, the officers review discipline handed out for on-field conduct. Player suspensions must be appealed in three days to the officers, and their decisions are binding.
