It is an aggravation of the issue Howard entered the game battling. Howard was trying to help his team, but he was clearly not himself, getting beaten time and again by Tee Higgins. The Amazon cameras spotted him on the sideline with his leg wrapped. His night is likely through. He will have 10 days to get healthy for Week 5 against the Jets.
