Robert Eugene Davis, 22, who had pleaded "no contest" to felony assault charges in February, will receive one day credit for time already served and must pay $75 a month for three years of supervised probation, according to a report by Chief Deputy District Attorney Steve Wagstaffe.
Mr. Davis must also abstain from alcoholic beverages, undergo chemical testing, submit a DNA sample, attend counseling, pay $280 in fines, pay the victims restitution of a yet to be determined amount, and submit to warrantless search and seizure by police, prosecutors said.
The victims were two men who had taken the train from a Giants baseball game and had gotten off in Menlo Park. Also getting off the train there were Mr. Davis and his co-defendant and judo champion Matthew Walker, who engaged one of the victims in a martial-arts conversation that evolved into sparring that got "very rough," prosecutors said.
That victim said he wanted to stop but Mr. Walker continued and "severely beat" him, prosecutors said. (Mr. Walker received a six-month jail sentence in February that included penalties similar to those handed down to Mr. Davis.)
Mr. Davis took a cell phone from the second man who, seeing what was happening to his friend, tried to capture the fight on video, prosecutors said.
The man under attack by Mr. Walker suffered a broken leg. The man attacked by Mr. Davis was knocked unconscious. Both men had facial lacerations, prosecutors said.
