Attorney Andrew Leavitt appeared on Carter's behalf Monday before a North Las Vegas judge who postponed action in the case until April 18. Carter didn't appear.
Leavitt says Carter "adamantly denies" adding $5 chips to three bets after the dice already rolled.
The 24-year-old former North Las Vegas high school football star was arrested late on March 9 at the Texas Station casino in North Las Vegas, where police say security video showed the acts.
Carter faces three felony charges of fraudulent acts in a gaming establishment that each carry a possible sentence of one to six years in prison and a $10,000 fine.
