Gronk’s Injury “Not Believed to Be Serious” (VIDEO)

The Patriots are no longer undefeated. But it doesn't really matter. The dream of the perfect season is done, but it doesn't really matter.

The thing that does matter is the health of Rob Gronkowski. The Pats lost Gronk last night late in the game against Denver with a knee injury. Here is the play that cost Gronk the rest of the game.

Gronk was down in obvious pain and was carted off the field. It's the same knee that he injured a few years ago. The good news here? His knee wasn't planted in the ground, so people are hoping his ACL isn't torn.

The Patriots got some good news after the game as we saw Gronk walking around the tunnel on his own power. He also boarded the team plane without crutches or a walking boot.

That's huge news for the Patriots, who have already lost Dion Lewis, Julian Edelman and Danny Amendola this season.
