Hustle plays in the NBA can lead to players jumping into the crowd and accidentally making contact with fans sitting in the front row.  We always applaud hustle plays, but it's also important to be aware if you're sitting up close, especially if you're a pro athlete.

Sunday in Miami, for example, Aleksander Barkov was sitting close to the court when Dwyane Wade went into the crowd trying to keep the ball in play and he Barkov ended up taking a knee from Wade.

For those worried about Barkov, you'll be happy to know he's fine and is still a fan of Wade and the Heat.
When fans realized Barkov was the person who took the knee to the head, though, they were freaking out a bit.
