Denver Broncos tackle Quinn Bailey left practice in an ambulance Wednesday with an air cast on his right leg.
Trainers ran out and helped to load the 28-year-old veteran onto a cart after observers said his leg got rolled up on.
Bailey joined the Broncos as an undrafted free agent in 2019 and appeared in all 17 games last season.
The 6-foot-6, 323-pound lineman has appeared in 31 games, with one start in each of the past two campaigns.
