Monroe pleaded no contest to a lesser charge of obstructing a passageway as part of an agreement. He received deferred adjudication involving one year of probation and 24 hours of community service, Roark said.
"I think he's very happy that it's over and with the result," Roark said in a phone interview. "He's looking forward to hopefully helping the 'Horns win a national championship."
Texas faces Alabama in the Citi BCS National Championship Game at the Rose Bowl on Jan. 7.
Coach Mack Brown suspended Monroe indefinitely following the arrest. A Texas football spokesman said Brown was on a recruiting trip and unavailable for immediate comment. The coach plans to meet with Monroe and his parents, with an update on his status likely for early next week.
Monroe had emerged as a key special teams performer early in the season, returning two kickoffs for touchdowns and setting a Texas season and career record in the process.
