VIDEO: LA Galaxy star Beckham facing 4-match ban after sparking all-in brawl
The former England skipper was restrained by team-mates - and even shoved San Jose's mascot as things turned uglier at the final whistle.
It all kicked off in injury time when Beckham was booked for kicking the ball at a San Jose player on the ground AND the referee.
Tempers continued to flare after the final whistle.
ESPN TV pundit Scott French said: "Beckham should be looking at three or four games out.
"Kicking the ball at Sam Cronin and the referee was bad enough but his post-game actions were something else."
