This pickup soccer match wasn’t very “friendly,” after all.

Police are hoping to give a soccer player a whole lot more than a red card after he allegedly stabbed another player in the thigh during a game in the Mission district Monday.

The men got into some sort of disagreement about 1 p.m. during the match at the Garfield Square soccer field near 25th and Harrison streets, police Sgt. Daryl Fong said Tuesday.

That led to a brawl in which one of the players sunk a knife into another player’s thigh, Fong said.

The victim remained at San Francisco General Hospital on Tuesday, but police said his injuries are not considered life-threatening.

The player-turned-hooligan fled after the attack and has not been found, Fong said.

Police are asking witnesses to come forward.

Another assault occurred during a soccer match in San Francisco in March when a referee was briefly knocked out at Crocker Amazon Park after a player who was enraged by a call delivered a “martial arts kick” to the ref’s face, police said.

“The suspect fled when he saw the victim go down and not get up right away,” police said at the time.
