When WWE took "Monday Night Raw" to Washington, D.C., in 2009, Shaquille O'Neal was a special guest referee and wound up stealing the show.

Shaq ripped off his striped shirt and climbed in the ring with WWE superstar Big Show, whose real name is Paul Wight. O'Neal got the better of Big Show then, but a rematch could be in store.

O'Neal, who is listed at 7-1 and 325 pounds, and Big Show, who is 7-0, 440 pounds, talked Wednesday on the red carpet before the ESPYs and agreed to face off at next year's WrestleMania in Shaq's old stomping grounds of Orlando, Fla.
It was a friendly exchange, unlike their meeting in 2009 when they exchanged choke grips.
That standoff was revisited earlier this year when O'Neal made a surprising appearance at WrestleMania 32.
The agreement has been made between the two giants. Now the ball is in the court of WWE chairman Vince McMahon.
