Bears linebacker Jerrell Freeman has been suspended 10 games for a repeat violation of the league’s policy on performance-enhancing drugs, the team announced Monday afternoon.

Freeman issued a statement after his suspension, in which he admitted to memory loss from a head injury and acknowledged his career may be over.

Freeman is currently on injured reserve but is still allowed to begin serving his suspension immediately. He was suspended for four games last November for a first-time violation. With the 10-game suspension, Freeman will forfeit $1.875 million in game checks for the remainder of this season.
