LOS ANGELES -- UCLA freshman Shabazz Muhammad has been declared ineligible for competition after a lengthy NCAA investigation determined he had committed a violation of the NCAA's amateurism rules.

An NCAA news release Friday night stated: "Muhammad is not eligible to compete in (Friday's) game due to violations of NCAA amateurism rules," and it made no mention of future games.

UCLA athletic director Dan Guerrero said Friday night before UCLA's season opener that he knows only that Muhammad, the No. 2 overall recruit in the ESPN 100 last year, has been declared ineligible at this time.

On Tuesday, Muhammad's family released a statement to the Los Angeles Times.

"Last Friday, the NCAA released a Press Release which not only was wrong in its conclusions but which also inaccurately portrayed the investigation process in this case," the statement read in part. "For over a year, the NCAA has known all of the relevant facts related to its ruling last Friday. Prior to the unofficial visits in question, Ron Holmes and Benjamin Lincoln received approval from NCAA (through its member universities) for Mr. Lincoln (who has had a continuous close friendship with Shabazz's family since 2007) to pay for airline tickets and hotel rooms. In 2010, Mr. Holmes openly and honestly revealed to the NCAA the source of the payments on the NCAA's compliance form."

After the No. 13 Bruins' 86-59 win over Indiana State, which Muhammad watched from the bench, UCLA coach Ben Howland called the ruling "very disappointing."

"I feel terrible for Shabazz because he is a great kid and has had a phenomenal attitude in dealing with this review by the NCAA," Howland said. "We were very optimistic that he was going to be cleared today, so we are very disappointed for him. We're hopeful that it's something that is going to be worked out in the near future.

"When he is able to play, he's going to add a big boost for us. He's a guy who can really score, really shoot and he's a great rebounder."
