Tennis Player Loses Point, Smashes Head with Racquet . . . and Bleeds

Indeed, the sequence indicated by the post title seems logical enough. Some of you may have even cried out, “Way to title the post, Captain Obvious.”
Keep in mind, though, that not everyone grasps cause-and-effect thoroughly.
Take tennis player Mikhail Youzhny, for example. This cringe-inducing clip (2m, 12s) is a testament to that fact. The first few seconds are buggy but it clears up; watch at least the first 52 seconds to get the, uh, full impact.
Ouch.
