According to Mike Garafolo of FOX Sports, it looks like Patriots tight end Rob Gronkowski suffered a torn ACL during today’s game against the Browns.
Source says Rob Gronkowski suffered what's believed to be a torn ACL. MRI tomorrow to confirm. Not surprising but another bad break for him.

Huge blow for the Pats. Getting Gronk back was a big lift for them. Now they’re back to square one.
