Mims (ankle) was a limited participant in Denver's practice Wednesday, Aric DiLalla of the team's official site reports.
Mims popped up on Wednesday's injury report with an ankle injury, casting doubt on his availability for Sunday's matchup versus the Chiefs. If he ends up being unable to play, Lil'Jordan Humphrey could see increased playing time at receiver, while Kris Abrams-Draine would likely handle punt return duties.
