When Rob Gronkowski began practicing at the outset of training camp without a stint on the Active/PUP list as many had expected, most believed that he would presumably be 100% by the time week one of the regular season arrived.
As it turns out, this may not be the case. Gronkowski has continued to be limited in practice sessions. He's participated in most individual drills, but has stayed away from contact and team work.
Mike Florio of ProFootballTalk.com has a further update on the rehab of Gronkowski:
Per a source with knowledge of the situation, Gronkowski's anticipated Week One availability sits at 50-50, with perhaps a shade above the even-money proposition. It's not a surprise; given the many surgeries and complications Gronkowski has endured in the past two years, there's no reason to be reckless with his health.
Following the injury, we knew that the Patriots would bring back Gronkowski slowly and we knew the Patriots wouldn't put him on the field if he were anything less than 100%. Still, all along, it had been expected that Gronk would be ready for Miami. The fact that there is now considerable doubt to that expectation is news-worthy.
