EXCLUSIVE

Turns out Scottie Pippen doesn't need Michael Jordan to win after all -- 'cause the NBA legend KO'd a guy in Malibu last night ... TMZ has learned.

Here's what we know ... 47-year-old Pippen was outside Nobu in the 'Bu when he got into a fight with another guy.

Not clear at this point what started the altercation -- but we know it ended with the other guy getting so injured he was taken to a local hospital by ambulance.

FYI: Pippen is 6'8" and well over 200 lbs.

Police were called to the scene, but by the time they got there ... Pippen had left.

Scottie won 6 NBA titles with the Chicago Bulls ... and Jordan. None without MJ.
