CLEVELAND — Cleveland Browns nose tackle Shaun Rogers has pleaded not guilty to a concealed weapons charge after authorities say he tried to carry a loaded handgun through airport security in a carry-on bag.

Rogers' attorney Patrick D'Angelo says his client entered the plea Saturday in Cleveland Municipal Court. The charge carries a maximum penalty of 18 months in prison.

The 31-year-old apologized to his fans and his team Friday after spending a night in jail, saying he didn't mean to take the gun into Cleveland Hopkins International Airport. Rogers told police he forgot the gun was in his bag when he attempted to fly to Texas on Thursday.

D'Angelo says Rogers planned to fly to Houston later Saturday to spend Easter with family and will make sure "to check everything."
