The Bears put inside linebacker Danny Trevathan on injured reserve Wednesday.
He can return to game action starting in Week 4.
After struggling in the first part of last season — and raising questions about his fitness — Trevathan reported to camp in what general manager Ryan Pace called “great shape.” The linebacker credited a boxing regimen during the offseason. Trevathan missed time in mid-August, though, with what the team called knee soreness.
Surprisingly, Trevathan started the Bears final preseason game, playing 11 snaps against the Titans. He intercepted Matt Barkley’s pass on what proved to be his last snap of the night, returning it out of bounds along the Titans sideline.
