There's a fantastic welterweight match-up brewing for the upcoming UFC 123 event, as Showdown Joe Ferraro brings word that Rory MacDonald and Matt Brown are likely to hook 'em up on Nov. 20.

No venue has been made official at this time.

MacDonald (10-1) saw his undefeated streak snapped at UFC 115: "Liddell vs. Franklin" back on June 12 in Vancouver. "The Waterboy" looked to be having his way with division standout Carlos Condit until "The Natural Born Killer" overcame adversity and secured a TKO stoppage late in the final frame.

It was his first defeat as a professional fighter and just his second appearance inside the Octagon. Prior to submitting Mike "Joker" Guymon in his UFC debut, MacDonald ran roughshod over the competition in King of the Cage (KOTC).

Like the Canadian, Brown (11-9) is hoping to rebound from a recent defeat. "The Immortal" was unable to escape the crafty submission game of Chris Lytle, who secured the tap on the former Ultimate Fighter (TUF) 7 contestant at UFC 116: "Lesnar vs. Carwin" back in July.

It was Brown's second straight submission loss since stringing together three consecutive wins. Despite his ability to entertain fans with his balls-to-the-wall style, there has to be some sense of urgency in the Brown camp based on the promotion's unfavorable treatment of fighters who drop three straight fights.

UFC 123 is expected to be headlined by a main event pitting former light heavyweight champion Quinton "Rampage" Jackson against fellow ex-champion Lyoto "The Dragon" Machida.
