UPDATE (12:20 a.m. ET): Good news, New England Patriots fans. The team apparently believes Rob Gronkowski’s knee injury isn’t serious, according to multiple reports.

We obviously won’t know Gronkowski’s status for sure until after his MRI, but the tight end was walking around in the Patriots’ locker room under his own power after the 30-24 overtime loss, according to those on the scene in Denver, including NESN.com’s Doug Kyed.

ORIGINAL STORY: The New England Patriots couldn’t afford to lose many more players entering Sunday night’s game. But that’s exactly what happened against the Denver Broncos.

The Patriots and their fans watched a potential nightmare scenario unfold late in the fourth quarter when Rob Gronkowski went up for a Tom Brady pass. Broncos safety Darian Stewart knifed in to deliver a shot directly to Gronkowski’s knee, leaving the Patriots tight end writhing on the turf in pain.

Here’s a slow-motion look at the play, which shows Gronk’s knee whipping in an ugly direction.

Gronkowski was carted to the locker room, and the Patriots quickly ruled him out of the game.

The 26-year-old was seen walking to the Patriots’ locker room under his own power, however. He received X-rays on his knee, according to NFL Network’s James Palmer.
