Campus police arrested the freshman guard after he carried a BB gun into his dorm room, the school said in a statement, according to the Clarion Ledger.
"I am aware of the situation involving Craig bringing a BB gun into the dorm, which is a misdemeanor," MSU coach Rick Ray said in the statement. "Craig did not point it at anyone or toward anyone. Craig realizes the severity of his actions, is extremely remorseful and fully understands that he must be held accountable. There will be disciplinary action carried out once I have all the facts and details."
Sword was last season's Gatorade Player of the Year in Alabama.
The Bulldogs, already thin at the guard position, likely lost freshman Jacoby Davis for the season after he suffered a knee injury Monday.
According to the newspaper, Sword was likely to start this season at shooting guard and see time at point guard with Davis out.
