MMApayout has the scoop via MMAWeekly:

Anheuser-Busch is stepping up its involvement in MMA by making UFC middleweight champion Anderson "The Spider" Silva and former UFC light heavyweight titleholder Chuck "The Iceman" Liddell spokesmen for the Bud Light brand.

Silva’s manager, Ed Soares, told MMAWeekly Radio, "We just finalized a deal with Anheuser-Busch. Him (Silva) and Chuck Liddell are going to be spokespeople for Bud Light and Anheuser-Busch here in the U.S."

The campaign is set to hit 4,000 convenience stores throughout the country immediately as well as include billboards and television commercial appearances.
This is big news for MMA fighters...could you imagine Chuck Liddell or Anderson Silva possibly doing a Bud Light commercial. That would be huge exposure, and could open the door for more big named sponsors to follow suit. Fighters that obtain sponsorship from these blue chip sponsors could make massive amounts of money, while promoting the sport of MMA to an even larger audience without even having to fight.
