Indianapolis Colts tight end Brandon Williams suffered an injury while blocking on a punt in the first half of Thursday's game against the Denver Broncos.
Mike Chappell of Indy Sports Central tweeted that trainers were "being VERY careful" placing him on a cart and "keeping him very still."
Jason La Canfora of CBS Sports noted Williams has a "pre-existing spinal condition" and called it a "scary scene" as he was stabilized before he was carted off the field.
According to Nick Griffith of Fox 31 Denver, the Colts said the injury was to Williams' head, clarifying "he did have activity in his limbs and was strapped on stretcher for precautionary purposes.
