In his first public sighting since announcing his retirement from the NFL, Randy Moss was checking out Mixed Martial Arts competition.

The former Vikings and Patriots star was among the celebrity-packed crowd in Philadelphia over the weekend for Ultimate Fighting Championship 133.

The pride of West Virginia, Moss has received calls from at least two teams since he announced the end of his 13-year career, but so far has stayed retired.

Moss wasn't ringside, but was spotted by the Philadelphia Daily News in the Wells Fargo Center along with U.S. men's national team soccer goalie Tim Howard.

Mickey Rourke, star of "The Wrestler," Charles Barkley of TNT and boxing's Bernard Hopkins were also in the house for Dana White's favorite sport.

Barkley, who spends his summers in Philadelphia, was also observed partying with former Pistons and Celtics star Rasheed Wallace a few days before UFC 133.
