The man who claims he was attacked by Draymond Green has already lawyered up -- and says he's demanding justice for the "unprovoked, unnecessary attack" that changed his life forever.

Attorney Corey Minor Smith says she's officially representing Michigan State football player Jermaine Edmondson -- who claims the NBA star attacked him outside of a bar early Sunday morning.

"My client is a student-athlete who was punched and assaulted by Mr. Green in an unprovoked, unnecessary attack," Smith said.

"His life has been forever altered by the events of that weekend."

Smith says 22-year-old Edmondson is "fully cooperating with the authorities investigating this unfortunate situation" and welcomes a "full and thorough investigation."
