Per ESPN reporters, the injury is not as grave as it appeared on the field.
"Sources tell me pending MRI, Rob Gronkowski's injury is not as bad as it looked," Dianna Russini tweeted.
Adam Schefter followed that report with, "More testing likely and further updates ahead, but one source just texted this on Gronk's leg injury: 'Doesn't appear to be serious.'"
"Per source, Patriots TE Rob Gronkowski's injury is not believed to be serious. More tests coming," wrote NFL Network's Albert Breer.
"Patriots do not believe that TE Rob Gronkowski suffered a serious knee injury, source said," NFL Network's Ian Rapoport tweeted. "More tests tomorrow, but a sigh of relief."
Multiple reports from the locker room have made it clear that Gronkowski is not wearing a brace, he has mobility in his knee, and he's walking around. He has not been made available to the media.
Even if the injury sidelines Gronkowski for the upcoming weeks, any non-season-ending report is good news. The Patriots already lost key offensive players Nate Solder and Dion Lewis for the season, while Julian Edelman looks to return for the playoffs and Amendola aims to return in the upcoming weeks
If the Patriots are able to bring back Gronkowski alongside Edelman in time for the playoffs, this team will be as dangerous as any in the league.
We'll continue to provide updates as Gronkowski goes through his tests.
