Dana White talks champ vs. champ...

UFC president Dana White said if both UFC Georges St-Pierre and Anderson Silva prove successful in their next title defense, they could meet in a rare champion-vs.-champion fight later this year.

"If they both win their fights, that fight makes all the sense in the world," White said.

Silva (27-4 MMA, 12-0 UFC) looks to defend his belt for a record eighth time when he meets Vitor Belfort in the headliner of next month's UFC 126 event. St-Pierre (21-2 MMA, 15-2 UFC) goes for his sixth straight title defense against Jake Shields in April at UFC 129.

Both champs are expected to win.

"If that happens, then we're probably going to do that fight," White said. "I don't like guys fighting each other at different weights until they've done what those two have done, and they've both done it."

But White expects the 170-pound St-Pierre to make a permanent move to 185 pounds if he were to fight Silva, marking his debut in the middleweight division.

"Georges St-Pierre would move to 185 and stay at that weight and not go back to 170," White said.
