Denver Broncos safety Rahim Moore could be out for several weeks with a leg injury, according to a report.
The 23-year-old sustained the injury during the first quarter of his side's win over the Kansas City Chiefs on Sunday.
Moore was taken to the locker room and did not return to the field, and underwent tests which failed to diagnose the problem, but it is severe enough to keep him out of action for several weeks, reports the Denver Post.
The Broncos are 9-1 in their season after week 11.
