A couple of well-known UFC veterans were in action over the weekend as Mike Whitehead and Jeremy Horn both picked up victories in their fights at IFC: "Extreme Challenge" last Saturday night (July 10) from the Soaring Eagle Casino in Mt. Pleasant, Michigan.

Whitehead (25-7) stopped fellow Zuffa vet Chase Gormley with a fourth-round technical knockout to capture the promotion's heavyweight strap. Gormley (7-3) was a last-minute replacement for Jeff Monson after "The Snowman" withdrew due to scheduling conflicts with Impact FC.

Horn scored his fifth straight submission win since leaving the UFC in early 2009. "Gumby" choked out Sean Salmon in the first round to push his record to a staggering 85-19-5. Salmon falls to 18-11 with the loss.

Tim Ruberg, Anthony Lapsley and Kelly Warren also picked up wins in Mt. Pleasant.
