These two don't like each other.

The Ultimate Fighter (TUF) "Sm-Ashes" coaches George Sotiropoulos vs. Ross Pearson are ready to settle their differences inside the Octagon in tonight's (Dec. 14, 2012) main event, part of the UFC on FX 6 live finale emanating from the Gold Coast Convention and Exhibition Centre in Broadbeach, Queensland, Australia.

See our comprehensive preview and breakdown of their heated 155-pound rivalry here.

There's a lot more on the line in this fight than just TUF bragging rights. Pearson (13-6) suffered a technical knockout (TKO) loss to Cub Swanson earlier this year at UFC on FX 4 in Atlantic City, NJ. "Sots" (14-4), meanwhile, has been flying under the radar since back-to-back losses to Dennis Siver and Rafael dos Anjos.

This could be the rebirth -- or undoing -- for both struggling fighters as they return to lightweight.
