Sherk (32-3-1), a former UFC lightweight champion, was stripped of his title following a July 2007 victory over Hermes Franca after testing positive for steroids. The positive test, which was appealed, was ultimately upheld and Sherk returned from his six-month suspension in May to take on lightweight champ BJ Penn. Penn topped Sherk via third-round TKO and now the former UFC 155-pound champion, whose lone losses have come against Penn, Georges St. Pierre, and Matt Hughes, will look to rebound against Griffin.
Griffin (12-1) opened his MMA career with eight-straight victories, including a win over urijah Faber and a UFC debut victory against David Lee, but sufered his first career loss to Frank Edgar at UFC 67 in early-2007. He’s since bounced back with four straight victories inside the octagon over Clay Guida, Thiago Tavares, Gleison Tibau, and Marcus Aurelio.
The UFC also confirmed that Hermes Franca will take on Gleison Tibay and Josh Burkman will face Pete Sell at UFC 90.
