Rob Gronkowski is back, folks.

Just two weeks ago, the New England Patriots tight end was writhing in pain on the Denver Broncos' turf after suffering what appeared to be a serious knee injury. Gronkowski missed just one game, though, returning to action Sunday night against the Houston Texans despite entering the weekend as a game-time decision.

For anyone questioning if Gronk wasn't 100 percent for this game, here's proof he's doing just fine:

That 1-yard touchdown catch from quarterback Tom Brady was Gronkowski's 10th TD grab of the season, marking the fifth time in six NFL seasons he's recorded 10 touchdowns or more.

His patented celebration apparently isn't too rusty, either.
