UFC officials announced the fight to Australian newspaper the Daily Telegraph on Tuesday.
Both Beltran and Perosh will be looking to get back on track after recent losses.
Beltran returned to the UFC at a new weight class in July, but came up short after an all out war against James Te Huna.
Meanwhile, Anthony Perosh found himself on the wrong end of a knockout at the hands of debuting light heavyweight Ryan Jimmo, in one of the fastest KO’s in UFC history.
The two light heavyweights will meet at the TUF: The Smashes finale as part of the undercard for the show headlined by coaches Ross Pearson and George Sotiropoulous.
