Video: Lions' Jamie Collins Ejected vs. Bears for Head-Butting Ref in the Chest

Detroit Lions linebacker Jamie Collins was ejected in the first half of the team's game against the Chicago Bears after head-butting an official. 

According to Patrick Finley of the Chicago Sun-Times, Collins had been attempting to demonstrate a hit but was immediately flagged for the action and tossed from the game. 

Collins' agency, DEC Management, reacted to the ejection (warning: NSFW language):

There was mixed reaction on social media after the ejection:

"Well, find a blocking dummy if you're gonna do something like that," former NFL director of officiating Mike Pereira said during the Fox broadcast, per Rod Beard of the Detroit News. "But don't use the referee. If you're gonna use the referee to demonstrate a hit with the crown of the helmet you're in a little bit of trouble there. So he is ejected from the game, will be fined. Can't do any of that."

Collins, 30, signed a three-year, $30 million deal with the Lions this offseason to bolster their defense, though his debut didn't last long. 

The veteran registered 81 tackles (10 for loss), seven sacks, 10 quarterback hits, three interceptions, three forced fumbles and a fumble recovery for the New England Patriots in the 2019 season. He's played for the Lions, Patriots (in two separate stints) and the Cleveland Browns in his career.
