Chicago Bulls point guard Derrick Rose said he used "extremely poor judgment" in posing for a photo flashing a gang sign.

The NBA's rookie of the year said in a statement issued through the Bulls that the photo circulating on the Internet was taken at a party he went to while at the University of Memphis.

It was "meant as a joke . . . a bad one, I now admit," Rose said.

Rose said he was "guilty of being young, naive, and of using extremely poor judgment," but has never been affiliated with a gang.

"I can't speak loudly enough against gang violence, and things that gangs represent," he said. "I sincerely apologize to all my fans for my mistake."

Rose, the overall No. 1 pick in the 2008 NBA draft who led the Bulls to the playoffs, was already under a cloud cast by an NCAA investigation of major violations at Memphis during the only season he played there.

In a letter to Memphis, the NCAA said an unknown person took the SAT for a player - with his knowledge - and that the player used it to get admitted. The governing body said the athlete played for the Tigers only in the 2007-08 season and the 2008 NCAA tournament. Only one person fits that description - Rose.

Jordan jersey swiped

An autographed Michael Jordan jersey was stolen from the home of San Antonio Spurs guard Tony Parker, the Bexar County sheriff's office said.

Detectives found a listing for the jersey on Craigslist that was posted by Christopher James Carolan, 22, of San Antonio. He was jailed on a separate burglary warrant and awaits charges in the jersey theft.
