Former UFC welterweight champion Matt Hughes would likely have jumped at the opportunity recently presented to Georges St-Pierre.

The current UFC 170-pound champion St-Pierre turned down a super-fight with Anderson Silva for a match with Nick Diaz.

Hughes, who announced his formal retirement last week, told MMAjunkie.com Radio that he regrets not being able to face Silva in a champion vs. champion match.

“I always wanted to go up to 185 to put the belts together,” Hughes said.

Instead of facing Silva, Hughes went on to become one of the best welterweights ever, scoring himself an induction into the UFC’s Hall of Fame.

Hughes is now working with the UFC to help keep the fighters from taking drugs or banned substances. As far as a possible “final” fight, Hughes said, “I will not come back and be in the Octagon again.”

Silva made it well known that he was ready to fight St-Pierre, but that he would not move down to 170 pounds. GSP stated his desire to stay at welterweight, and agreed to face Diaz later this year.
