Sage Northcutt was ridiculously ripped for his latest weigh-in (Pic)

Sage Northcutt faces the biggest test of his fledgling UFC career when he takes on Pfister at the Fight Night 80 event in Las Vegas.

Northcutt is currently unbeaten in his MMA career and Dana White has high hopes of pairing him up with big names in the heavyweight division. His rapid rise has drawn scorn from Pfister, and other quarters, and he has already been forced to defend himself from P.E.D claims. Northcutt says it is good, old-fashioned hard work and plenty of gym hours that have him in shape. This snap from Wednesday's Fight Night weigh-ins shows a marked difference between the lightweight competitors. Look at that right bicep! Goodness.
