Jens Pulver
In October 2006, at "UFC 64", Sherk won all five rounds using his superior wrestling and ground and pound and defeated Kenny Florian via unanimous decision to win the UFC Lightweight Championship. With this win, Sherk became the first UFC Lightweight Champion since Jens Pulver vacated the title in 2002. Sherk fought the bout with a torn rotator cuff and was forced to rehabilitate afterwards.
