UFC featherweight contender Chad Mendes was charged with battery Friday by the Kings County (Calif.) District Attorney's Office.
The charge stems from a physical altercation that took place on July 29 at a bar in Hanford, Calif. Mendes is a native and resident of Hanford.
The (Hanford) Sentinel first reported the story.
According to deputies of the Kings County Sheriff's Department, Mendes allegedly punched a patron in the face at Lacy Inn Bar.
Eyewitnesses told authorities that Mendes quickly exited the bar through a back door as law-enforcement officers arrived on the scene.
The 27-year-old Mendes is scheduled to be arraigned on Sept. 19. If convicted, he faces a $2,000 fine and six months in jail.
Mendes has a professional record of 12-1. His lone loss came on Jan. 14 when 145-pound champion Jose Aldo knocked him out in the first round.
In his most recent bout, Mendes knocked out Cody McKenzie in the first round. That fight took place at UFC 148 on July 7.
