Joe Stevenson has dropped out of his upcoming lightweight showdown with Takanori Gomi at “UFC on Versus 2” due to a knee injury and Tyson Griffin will step in to face the former PRIDE champion at the August 1 event.

The news comes according to a report on the Wrestling Observer.

Griffin is coming off of a split decision loss to Evan Dunham at UFC 115, and has gone 7-3 in his ten appearances in the UFC. The Xtreme Couture trained fighter’s victories came against Hermes Franca, Clay Guida, Rafeal Dos Anjos, and Gleison Tibau, while his only losses have been to former champion Sean Sherk, current champ Frankie Edgar, and Dunham.

Gomi made his Octagon debut at UFC Fight Night 21 against Kenny Florian. In the third round, Florian submitted the Japanese superstar with a rear-naked choke. Gomi is looking for his first victory in the UFC after competing in Sengoku and various promotions since the fall of PRIDE FC.

UFC on Versus 2 will take place on August 1 from the San Diego Sports Arena.
