URBANA – University of Illinois basketball player Jamar Smith admitted to police that he drank three beers, according to a prosecutor. But Smith's lawyer denied the accusation on Wednesday.

Smith, 21, turned himself in on a warrant, posted bond and was released Tuesday. Earlier that day, the Champaign County state's attorney's office filed a petition to revoke Smith's probation and obtained the warrant for his arrest, with bond set at $25,000.

The petition accuses Smith of violating his probation by drinking alcohol Friday.

Smith was sentenced in May 2007 to two weeks in jail and two years of probation after he pleaded guilty to a charge of aggravated driving under the influence of alcohol causing great bodily harm. The charge stemmed from a Feb. 12, 2007, crash that injured teammate Brian Carlwell.

Assistant State's Attorney Dan Jackson said in court Wednesday that a condition of the probation was that Smith refrain from drinking alcohol. The prosecutor said Champaign police encountered Smith early Friday outside a campus bar and detected an odor of alcohol. Smith admitted drinking three beers, he said.

At the request of Smith's Attorney, Mark Lipton, Judge Richard Klaus set a hearing on the petition for revocation for Sept. 17. Lipton entered a general denial to the petition. The judge said the hearing decision will be based on a preponderance of evidence.

If Smith's probation is revoked, he could be resentenced to probation, jail or imprisonment up to 12 years.
