Crawford's suspension will last at least through the NBA Finals. He apparently will have to meet with Stern after that to discuss reinstatement.
NBA spokesman Tim Frank said the league has not ruled out any penalties against Duncan. The Spurs said they did not yet have a comment.
Stern said Crawford's actions "failed to meet the standards of professionalism and game management we expect of NBA referees."
"Especially in light of similar prior acts by this official, a significant suspension is warranted," Stern said in a statement. "Although Joey is consistently rated as one of our top referees, he must be held accountable for his actions on the floor, and we will have further discussions with him following the season to be sure he understands his responsibilities."
I’m glad to see this douchebag get what he deserved.
