Cerrone has served as a short-notice replacement in two of his three UFC fights, but he's found a dominant path to victory in all of them, impressing many as he's gone undefeated in the Octagon, most recently over the highly-touted Charles Oliveira. Siver, meanwhile, may be on the cusp of a title shot with his four-fight winning streak, but his strength of schedule in those four fights may be of some concern, as none of his opponents, except for George Sotiropoulos, were anywhere close to a title shot.
Tyson Griffin will look to repeat the success he had in his first 145 lb. UFC fight back in March, when he won a majority decision over Manny Gamburyan (Griffin competed at 145 lbs earlier in his career). The win snapped a potentially devastating three-fight losing streak for the 4-time fight-of-the-night bonus winner. Palaszewski will be making his UFC debut after a 10 year career on the midwest circuit and with other notable promotions including the IFL and WEC. "Bartimus" saw a four-fight winning streak of his own, snapped by Kamal Shalorus in a split decision loss at the final WEC event back in December of last year.
