He's the rock star of professional wrestling, but don't ask him to get in the ring with Pacman.
John Cena claims he'd be on the wrong end of a quick beatdown at the hands of boxer Manny Pacquiao.
The nine-time WWE champ was asked by ABS-CBS News (Manila, Philippines) about a possible match-up with the Filipino boxing hero.
"I think it would be very quick, and the decision would be obvious," Cena said. "Manny Pacquiao will knock me out in the first round."
Pacman has other knockouts to worry about, namely new friend Paris Hilton:
Pacquiao, who's a congressman in the Philippines, a singer, and all around man of the people, has the personality to be huge in the WWE. Cena says Pacquiao's quickness would be a huge advantage in the wrestling ring.
"If Manny will enter the WWE, I would have to work a lot on my quickness. He is lightning quick," Cena said. "So just give me a little bit of warning if he decides to (enter the WWE)."
Cena is listed at 6-1, 240 lbs. Pacquiao checks in at 5-6 1/2 and 145 lbs.
WWE's next big event has Cena entering the ring against rival CM Punk in a battle that will determine who really is the undisputed WWE champion.
