He will be fine, will be ready for next year. It's nothing like a " Bill walton " type of injury/ injury's. Gronk will be back at 100% next year, took risk, rushed back and re-injuryed arm. More like RG3 than Walton.
As for this year, awful news...This hurts the Pats chance against 49ers in Superbowl.
You heard Brady say post game/ feild interview, " Our game planned got tossed after Gronk and Woody went out. "
Pats need Gronk to open passing lanes and keep safety at home.
