CLEVELAND — Myles Garrett has been slowed down just when the Browns need him most.

Cleveland’s dynamic star defensive end and the NFL’s leader in sacks will miss Sunday’s game against Philadelphia — and maybe more — after testing positive for COVID-19, dealing the Browns a major blow as they try to end an 18-year playoff drought.

The Browns (6-3) won’t have Garrett against the Eagles and there’s no predicting when he’ll be back.
