DETROIT -- Detroit Lions defensive end Trey Flowers is in the league's concussion protocol and center Frank Ragnow is being evaluated for a concussion, Lions coach Matt Patricia said after the team's 35-27 loss to the Dallas Cowboys on Sunday.
Both suffered the injuries in the fourth quarter. After the game, Flowers was not allowed to speak with the media -- part of the league's policy with the protocol.
Flowers appeared to be in considerable pain as he was helped off the field but seemed to be moving OK in the locker room after the game.
