When Chicago Bears linebacker Danny Trevathan exited Sunday’s game against the Detroit Lions in the first quarter, it was safe to assume that he wouldn’t be returning anytime soon.

Not after suffering a gruesome elbow injury, where Trevathan’s arm was bent awkwardly as he brought down Lions quarterback Jeff Driskel.

While Trevathan had an MRI done Monday, Bears coach Matt Nagy offered no official update of Trevathan’s injury during his Monday press conference. But he didn’t sound optimistic.

“Yeah. It’ not real pretty,” Nagy said, via NBC Sports Chicago. “But it’s a part of this game. You hate to see that, so we’ll see how that goes moving forward.”

Nagy wouldn’t rule out placing Trevathan on injured reserve. Though, to be fair, Nagy said during his post game press conference that they wouldn’t know anything for a “few days.” But injured reserve feels like a foregone conclusion at this point given the gruesome look at Trevathan’s elbow injury.

“It could be,” Nagy admitted. “Again, we’ll know more here in the next couple of days, but we’ll see where it goes as far as weeks are concerned.”

With the impending loss of Trevathan, that leaves the Bears down two defensive leaders. Defensive tackle Akiem Hicks, who sustained a dislocated elbow in Week 5, was placed on injured reserve shortly after and is eligible to return in Week 15 against the Green Bay Packers.

“They’re two of the more vocal guys on that side of the ball,” Nagy said. “When you lose a guy like Danny in the middle, that leadership part, you lose a little bit…

“It’s hard, just because there is so much between the two. Just their personalities in general – they’re both a little bit different, with how they handle their personalities. But they’re very similar on the field, leadership-wise. As we move forward here, we’ll have guys that are always ready and prepared and the coaches will have them the same way.”
