Detroit Lions linebacker Jamie Collins was ejected from Sunday's 27-23 loss to the Chicago Bears.
The veteran LB was thrown out of the game with 12:24 left in the second quarter for unsportsmanlike conduct. The score was tied 3-3 at the time.
Collins appeared to be complaining about Bears running back David Montgomery lowering his helmet on a run. The linebacker contacted an official in the chest with his helmet on the play leading to the disqualification.
Collins will not be suspended for the incident, NFL Network's Tom Pelissero reported Monday.
The free-agent addition played 19 of 25 snaps in his first game in Detroit before being ejected, per NextGen Stats.
