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, according to NFL Network's Ian Rapoport.

According to NFL Network's Ian Rapoport, Texans running back Joe Mixon will miss "an extended period of time" while dealing with a foot injury. Mixon had already been on the Texans' non-football injury list to start training camp, but Saturday's report added clarity to a potential timeline for the running back's return.

Aaron Glenn maintains optimistic outlook despite losing new quarterback to foot injury during Thursday's practice.
