Ultimate Fighting Championship competitor War Machine has been sentenced to a year in jail for violating probation after he assaulted people at two San Diego bars.

War Machine pleaded guilty Thursday to two felony counts of assault and to violating probation in a previous assault case. He has a professional fight scheduled for July 9 and was ordered to surrender for jail a week later.

Prosecutors say the 28-year-old fighter knocked away some bottles and glasses on a bar, cutting a bartender. He also got into a scuffle and punched a security guard.

His attorney says an acquaintance started one of the fights but War Machine failed to stop it. The fighter legally changed his name from Jon Koppenhaver.
