Gronkowski cont., "I want to be out there so badly to help my team." Judging from this, sounds doubtful on playing but it's still unclear.

Reiss, a reporter for ESPN, shared a follow-up answer from Gronkowski about whether he’ll play Sunday: “Yeah, it boils to a coaching decision, the medical team, and myself. We’ll all get together and collaborate and see where I’m at.”
Given that it’s the Patriots, it’s possible we won’t know for sure one way or another until close to the deadline on Sunday night.
