The Lawrence Journal-World reports that Supervising City Prosecutor Jerry Little confirmed the citation Monday afternoon.
The citation stems from a 2:37 a.m. Sunday police call to a Lawrence bar.
Police spokeswoman Kim Murphree says a male employee was punched twice and that two men received citations. Little says those citations show that Marcus Morris is scheduled to appear March 20 in Lawrence Municipal Court.
Morris had attended the Missouri-Kansas game with his twin brother, Markieff, a former Jayhawk who now plays for the Phoenix Suns. Markieff wasn't implicated.
A message left for the Rockets wasn't immediately returned Monday.
