The NBA is investigating whether Celtics forward Kevin Garnett should be suspended for Game 2 of the team's first round series against the Heat.

Garnett was ejected with 40 seconds left in regulation after elbowing Miami's Quentin Richardson during a sideline scuffle.

Garnett "is an actress and so is Paul," Richardson said. "I was going to take the ball out over there. That was what I was trying to do. I told our trainer Jay [Sabol] that [Pierce] is cool and he's doing what he always do, lay down like it's a season-ending injury, then he gets up and he's miraculously fine. He gets a breath, takes his time or whatever and he did the same thing.

"It should be a suspension [for Garnett]. We'll see. That's up to the NBA. But I've seen things like that in the past and people get suspended. I was cool. I was going to try going at him, but with me being restrained, that's what it was."
