Denver Broncos linebacker Drew Sanders injured a tendon in his foot Saturday in training camp. The injury will cause him to miss significant time and potentially put his availability for Week 1 in question,

In an alarming sight for an already-banged-up inside linebacker room, Dre Greenlaw pulled up with a grimace after covering J.K. Dobbins in team drills.

"Broncos LB Drew Sanders, an up-and-coming defender, suffered a tendon injury in his foot in practice that will keep him out an extended period of time, sources say post-MRI," Rapoport wrote on X. "Sanders is not expected back before the season begins and further testing will determine what's next."
