WEC stand-out Bart Palaszewski will follow number of 155ers’ lead and test the waters in a division ten pounds lighter than usual with his scheduled opponent only a single fight removed from making the same switch – Tyson Griffin (15-5). The two well-rounded featherweights will face off at UFC 137 as part of what is shaping up to be an incredible event headlined by George St. Pierre defending his belt against Nick Diaz.

The October 29 match-up was recently revealed by the UFC.

Though Palaszewski is 4-1 in his last five fights including a win over Anthony Pettis, the decision to drop down marks a move designed to give him more of a size advantage than was the case during a successful career at lightweight. The 28-year old has gone 35-14 in a career spanning nearly a decade with 27 stoppages including night-ending offerings against Zach Micklewright, Ryan Schultz, and Kyle Watson. The fight will also mark his debut in the Octagon

Xtreme Couture’s Griffin found success on the scorecards against former title-contender Manny Gamburyan last month at UFC Live 4 in his unveiling at 145 pounds after earning past victories over Hermes Franca, Thiago Tavares, Gleison Tibau, and Clay Guida before the UFC welcomed smaller weights with the addition of WEC’s roster.

It is expected Griffin vs. Palaszewski will join the preliminary portion of UFC 137 where other planned pairings include Brandon Vera vs. Eliot Marshall, Tim Credeur vs. Brad Tavares, and Sam Stout vs. Dennis Siver.
