What happened last night between that Laker's guy and the Maverick's guy? i was so scared they were fighting?

One of the maverics players pushed a laker player, Steve Blake down and away with two hands. He got up and they started exchanging words. people came over to break it up and one of the istant coaches got shoved towards the courtside seats while trying to stop players from fighting. 4 players were ejected for the fight, two from each team. A third laker player was ejected later in the game.
