Two NBA players threw vicious haymakers at each other in mid-game fight

Not smart, guys.

It's safe to say that the NBA office won't be very happy about this one.

In the middle of the third quarter of Tuesday's game between the Chicago Bulls and the Toronto Raptors, Robin Lopez and Serge Ibaka were involved in an altercation that saw the two throw a couple of fully-loaded punches at each other.

The fight started after Ibaka appears to push Lopez in the back, and Lopez responds in kind by knocking the ball out of Ibaka's hands. The two then scuffle as players and referees head their way to break it up.

Both players were ejected and are now facing suspension from the league.
