The Los Angeles Clippers have confirmed that star player Blake Griffin injured his right hand in a fight with a member of the NBA team's equipment staff during a weekend trip to Toronto.

According to an ESPN report, the power forward and equipment staffer got into an argument in a restaurant. Griffin hit the man, who then left the restaurant and went outside. Griffin followed him outside and hit him again.

The man's face was injured while Griffin suffered a fracture, according to ESPN. Griffin is expected to be out of action for four-to-six weeks.

In a joint statement, Clippers owner Steve Ballmer and coach Doc Rivers, who is also president of basketball operations, said Griffin has a spiral fracture of the fourth metacarpal in his hand.

"This conduct has no place in our organization and this incident does not represent who we are as a team," the statement said. "We are conducting a full investigation with assistance from the NBA. At the conclusion of the investigation, appropriate action will be taken."

Late Tuesday night, Griffin tweeted an apology for his actions.

With Griffin, 26, missing his 14th straight game as he nurses a quadriceps injury, the Clippers lost 112-94 to the Toronto Raptors on Sunday.

Considered a championship contender heading into this season, Los Angeles ranks fourth in the Western Conference with a 29-16 record.

Griffin is averaging a team-high 23.2 points per game, however they hung on to beat the Indiana Pacers 91-89 on Tuesday.
