The Detroit Lions say they've signed ex-Chicago Bears agent defensive end Israel Idonije to a 1-year contract and have released defensive end Freddie Bishop.
The team said Wednesday it isn't releasing terms of its contract with Idonije, a free agent.
Idonije has spent nine seasons with the Bears. He started 11-of-16 games last season and finished second on the team in sacks (7.5) behind Julius Peppers (11.5).
Idonije made 48 tackles (29 solo), had 7.5 sacks (68 yards) and one forced fumble last season.
