Rob Gronkowski has shed his cast and is in the rehab phase of his recovery from a broken arm. "No cast," Gronkowski confirmed. "It's been a lot of weeks now; now I'm just in the rehab part of it. Getting it better. Getting it stronger. Getting it totally healthy now. Just taking it day by day, basically, with the rehab. Week by week. Once I'm 100 percent healthy, I'm definitely going to grind, hit it, hit the upper body, get stronger, and get ready for the season."
