GUCCI MANE Gets a Big Block … STAGE CRASHER CRUSHED!!!

Gucci Mane‘s show came to a brief halt after a guy jumped on stage and got a little too close to the rapper for comfort … and got promptly destroyed by a body check.

Gucci was performing at Tuskegee University in Alabama Friday night when the guy crashed the stage, but before he could dance — or whatever he was doing — to the front … Gucci’s road manager, Snake, came flying in for the blindside block.

Another member of Mane’s crew then stepped in for the final takedown … and the show went on.

Gucci wrote … “Somebody Tried to Sack The QuarterBack last nite but shout out my road manager aka Fullback @atlsnake #OnGuard #EyesUp”

The rapper’s back at it tonight in Fayetteville, AR … and our advice to those in attendance — don’t hop on stage.
