The Pats star was in the crowd Sunday watching his pal Mojo Rawley get pummeled by Jinder Mahal during the 4th annual Andre The Giant Memorial Battle Royal. and then chose to step in when Jinder got in his own face.
The backstory: Gronk is buddies with wrestler Mojo Rawley (this bond appears to be legitimate, based on a post-match interview).
Gronkowski was seated ringside when Jinder Mahal, who was fighting Rawley, threw water on the star tight end.
WWE threw their WrestleMania 33 broadcast over to USA Network at 6PM, and that potion of the Kickoff kicked off with the fourth annual Andre the Giant Memorial Battle Royal.
In response, Gronk chose to step over the barricade and enter the ring.
Monday's grab by New England Patriots tight end Rob Gronkowski was certainly not a called play, but it was absolutely a playbook amusing moment.
Gronk has been helping Rawley train and apparently couldn't stand by when he got into a tight spot.
The Zubaz-loving bros have been friends since Mojo - then going by his real name of Dean Muhtadi - played football at the University of Maryland with Rob's brothers, Dan and Chris.
WWE announced that WrestleMania 33 became the highest-grossing event in the history of Camping World Stadium and broke the stadium's attendance record with 75,245 fans from all 50 states and 62 countries. He got in a 3-point stance in the corner of the ring, made some odd faces, and laid a licking on poor Mahal in the opposite corner.
Gronkowski, 27, had his third back surgery four months ago.
What did you make of the security guard not allowing Rob Gronkowski to get into the ring?
