Spartan of the week

At 43 years old, Randy Couture has decided to come out of retirement for a title shot against heavyweight champ Tim Sylvia. The two will battle it out in the Octagon in early March.

Sylvia is six foot eight and has to cut weight to make the 265 pound heavyweight limit. He's won his last six fights in a row, including two over Andrei Arlovski.

Couture, at 43, having already carved out a legendary career for himself in MMA, has nothing left to prove. But he craves the challenge and because of that desire to push himself, to test his heart and fighting spirit, I hereby declare that...

"Captain America," Randy Couture is our Spartan of the Week.
