Broncos wide receiver A.T. Perry ( ankle) remains on the physically unable to perform list, and inside linebacker Drew Sanders (foot) is set to miss an " extended period " after suffering a tendon injury Saturday. Denver coach Sean Payton indicated Sanders will be out for north of four to six weeks.

"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."

The Broncos are enduring some massive hits already in NFL Training Camp. Now Alex Singleton is the latest to go down.
