Paul "The Punisher" Williams has a tough task ahead in his scheduled rematch against Sergio Martinez on November 20 in Atlantic City. If Williams beats Martinez and captures the WBC middleweight title, he is still willling to return to the welterweight division for a big fight.

Williams was planning to return to welterweight prior to a deal being reached for the Martinez rematch. He left the division in 2008 after being unable to secure a big fight. All of his fights since then have been fought at junior middleweight or middleweight. If Mayweather or Pacquiao come to the table, Williams is ready to move down.

"If the money right and they give me enough time to get down, we're there. If one of them top guys like Mayweather or Pacquiao take me down to 147, then I'm there. I don't want to go there for some up and coming guy to gain a rep off of me. When I fought Margarito and beat him, they said this was the time for me to get the biggest fights," Williams told BoxingScene.com's Bill Emes.

"I had to give up my [WBO welterweight] belt because Michael Jennings was [ranked] number one and Miguel Cotto was number two. I couldn't get them to fight me but when I vacated the title and moved up to take a 154-pound fight, they're fighting for my title. So does that tell you?"
