It looks like the UFC could be giving fans another early Halloween treat this October after already announcing a handful of “sweet” match-ups for their October 29 return to Las Vegas.

According to a source close to the situation, has confirmed a brawl between scintillating strikers Sam Stout and Dennis Siver is planned for UFC 137 though nothing official has been inked yet. A win for either is likely to put them in the discussion for a crack at the top names in the division.

Stout’s last showing marked perhaps his most impressive performance to date at UFC 131 in Vancouver where put Yves Edwards to sleep in the first round with a “Knockout of the Night” winning strike. Though it was the first KO for “Hands of Stone” in the UFC, the win was the fourth in five fights for the Team Tompkins student and the ninth strike-based stoppage of his career.

Comparably, Siver is coming off a controversial decision win over Matt Wiman at UFC 132. The victory was the fourth consecutive instance of in-ring success for the powerful German kickboxer and added to a streak already including George Sotiropoulos and Spencer Fisher

UFC 137 is headlined by Georges St. Pierre‘s title-defense against Strikeforce stand-out Nick Diaz and will also feature Mirko “Cro Cop” Filipovic vs. Roy Nelson, Cheick Kongo vs. Matt Mitrione, and Hatsu Hioki vs. George Roop. The card is also rumor to involve a welterweight showdown between B.J. Penn and Carlos Condit.
