Gronk went up to make a grab across the middle when T.J. Ward dove at Gronk's knee with his helmet, spearing the tight end in the knee.
Gronk immediately fell to the ground and began holding his knee. He was slow to get up and eventually carted off.
The Patriots already ruled out Gronkowski for the remainder of the game. That's not surprising but it's also not good news -- ruling out someone that fast can often be an indication of the severity of the injury.
Hopefully Gronk's OK, but holding out hope that this isn't a severe injury might be delusional.
The NFL's got to figure out a way to eliminate these hits. I know we're avoiding ways to keep players safe by not having their heads hit, but as just about any NFL player will tell you, there's really nothing worse than a massive knee injury.
