Bears linebacker Danny Trevathan is likely facing a fine and suspension after a vicious helmet-to-helmet hit on Davante Adams in the third quarter of Green Bay's 35-14 win on Thursday.
Trevathan apologized for the hit after the game and said he will reach out to Adams.
The Packers receiver was stood up by Bears safety Adrian Amos after making a short catch on a third-and-goal from the 16-yard line.
Adams was fighting for more yards when Trevathan flew in with a wicked helmet-to-helmet collision that left Adams unconscious on the Lambeau Field turf.
The medical staff was immediately on the field and Trevathan was flagged for the illegal hit, giving the Packers an automatic first down.
Adams was taken off the field on a stretcher and taken to a local hospital to be evaluated for head and neck injuries.
He had movement in all of his extremities and gave fans a thumbs up while strapped to a backboard on his way off the field.
"None of this is intentional," Bears coach John Fox said following the game. "You never want to see anybody hurt, ours or theirs."
The Packers scored on the next play, but the thoughts of the Green Bay players were with their injured teammate. Packers receiver Jordy Nelson told NFL Network the hit was "tough to watch" and he hopes the injury-riddled Packers can get healthy because they're "running out of players."
"It's tough. He's a great teammate and a great friend of mine. I'm hopeful we'll get some good news," Packers quarterback Aaron Rodgers said of Adams' injury during an interview with NFL Network. "Tough shot to see, see your buddy get knocked out on the ground like that."
While Rodgers said he didn't appreciate Trevathan celebrating the hit, especially "when a guy gets carted off the field," but "trusts" Trevathan was not trying to intentionally injure Adams.
Trevathan said after the game he was sorry and that the hit was not intentional, but that probably won't help him avoid NFL discipline.
"Hopefully they see it wasn't intentional. I was just trying to make a play," Trevathan told reporters. "My main concern is he's OK.
Fans and media reacted angrily to the illegal hit on social media.
