LAS VEGAS » Denver Broncos safety Quinton Carter was confused by the rules of a craps game, and wasn’t trying to cheat before he was arrested at a Las Vegas-area casino, his attorney said Monday.

Defense attorney Andrew Leavitt called Carter’s arrest March 9 at the Texas Station casino in North Las Vegas the result of "an absolute misunderstanding."

"He was confused when he made the bet," Leavitt told The Associated Press. "He didn’t know how to play the game. He wasn’t trying to cheat anyone."

Leavitt appeared Monday before a North Las Vegas judge who postponed action in the case until April 18. Carter didn’t appear in court. Leavitt said his client was out of the country on Monday.

Carter faces three felony charges of fraudulent act in a gaming establishment. Security officials reported he was videotaped adding a $5 chip to three bets after the dice had already rolled. Carter denied wrongdoing when police arrived. Each charge carries a possible sentence of one to six years in prison and a $10,000 fine.

Leavitt said he was trying to negotiate a resolution of the case before Carter appears in court.

Carter also faces a warrant charging him with failure to complete counseling after pleading guilty in a 2011 misdemeanor marijuana possession case.

Leavitt said Carter completed the counseling but never turned in proof to the court. He has since taken another counseling course in hopes the charge will be dropped.

Carter posted a message on his Twitter account Friday apologizing for "any negative attention this has brought to the Broncos, our fans and the league." He said he was confident he will be cleared.

Carter attended Cheyenne High School in North Las Vegas and was an All-American at Oklahoma before being drafted in 2011 by the Broncos.

He started at free safety his rookie year in 2011, but injured a knee last summer and missed all but a few games of the 2012 season.
