DE LA HOYA'S INJURY MINOR.

Byline: Michael Rosenthal Assistant Sports Editor 

Oscar De La Hoya aggravated a chronic injury in his left hand during sparring Friday, giving him a scare because his rematch against Shane Mosley is scheduled for Sept. 13 in Las Vegas.

However, he and his handlers say the injury doesn't appear to be serious enough to threaten the fight.

De La Hoya, who had surgery to repair a broken bone in the hand two years ago, said he plans to rest it a full week and then resume sparring and hitting bags with the hand. He hasn't used it in training since Friday.

``When I felt the pain, I thought, `My gosh, do I have to postpone the fight?' '' said De La Hoya, who has yet to have the hand X-rayed. ``I said, `No, I trained too hard for this fight.'

``... The only one who can postpone this fight is me and I won't do it.''

Anthony Garcia, a sports therapist who works with De La Hoya, said he isn't concerned.

``Not at all,'' he said. ``There was very minimal swelling and the pain level has gone down. He'll be 100 percent at fight time or before.''

De La Hoya, the junior middleweight champion from Pasadena, postponed his fight with Fernando Vargas last year after he sprained the hand.
