It didn’t take long for Billy Quarantillo to get a new opponent for UFC on ESPN 7.

“Dana White’s Contender Series” season 2 signee Quarantillo (12-2 MMA, 0-0 UFC) will now face season 1 competitor Jacob Kilburn on Dec. 7.

Two people with knowledge of the situation informed MMA Junkie of the booking but asked to remain anonymous as the promotion has yet to make an announcement.

UFC on ESPN 7 takes place Dec. 7 at Capital One Arena in Washington D.C. The card airs on ESPN following early prelims on ESPN+.

Kilburn (8-2 MMA, 0-0 UFC) will replace former Cage Warriors champion Chris Fishgold, who withdrew from the event earlier this week for unknown reasons.

New York’s Quarantillo is riding a five-fight win streak entering his showdown with Kilburn. In his most recent fight in July, Quarantillo punched his ticket to the UFC when he defeated surging Arizonan Kamuela Kirk by third-round TKO.

In 2018, Kilburn was one solid performance away from being inked to the UFC. However, Bobby Moffett played the spoiler when he submitted Kilburn in the second round at DWCS 16.

Since DWCS, Kilburn has won back-to-back fights by TKO – both under the Island Fights banner. In his most recent outing in October, Kilburn finished Javanis J. Ross by strikes in 94 seconds.
