Rafael Nadal is facing off against Gilles Müller of Luxembourg in the Round of 16 at Wimbledon today and while he is favored to win, he stumbled before even getting on Court 1. Waiting in the tunnel with Müller before taking the court, Nadal began a pre-match warmup routine that involved him jumping and stretching his legs out. Unfortunately, he did it right in the open doorway, which has a frame that is significantly lower than the actual ceiling. So, of course, Rafa cracked his dome on it.
There's quite a thud when he makes contact, but he seemed OK and laughed at himself for his brief, spazzy moment. He is currently not smiling however, because he dropped the first two sets to the 14-seeded Müller before picking up the third set, 6-3. As of this writing, he's up 4-2 in the fourth set, hoping to push it to a fifth.
