A video has surfaced of Rob Gronkowski landing on his broken arm while partying at a Las Vegas nightclub.
Gronkowski is dancing shirtless on stage with a long black cast on his left arm. At one point, he does a WWE-style move on a friend, wrestles with him and then they both fall to the ground. Gronk pops right back up and keeps rocking. Some in the Boston media are criticizing the video as further proof of his immaturity, but we'll take it as a good sign that his arm is feeling frisky just three weeks after his latest surgery.
