todd duffeeUFC Heavyweight slugger Todd Duffee burst onto the scene with a record-breaking* knockout of Tim Hague at UFC 102 but has been force to withdraw from his second fight in the Octagon due to injury.

Duffee was scheduled to fight knockout artist Paul Buentello at UFC 107: “Penn vs. Sanchez” later this year and has been training in his new home of Las Vegas. Instead, Buentello will now possibly face towering Stefan Struve. With Struve having an excellent ground game and Buentello always looking to keep things standing, it would prove a classic striker vs. grappler match-up.

We’ll keep you up to date with any further updates. As for now, the rumored card is as follows:

Main card (televised):

Champ B.J. Penn vs. Diego Sanchez (for lightweight title)
Cheick Kongo vs. Frank Mir
Jon Fitch vs. Mike Pierce
Kenny Florian vs. Clay Guida
Paul Buentello vs. TBA

Under card (may not be broadcast):

Alan Belcher vs. Wilson Gouveia
Shane Nelson vs. Matt Wiman
Ricardo Funch vs. Johny Hendricks
Lucio Linhares vs. Rousimar Palhares
Edgar Garcia vs. DaMarques Johnson
Kevin Burns vs. T.J. Grant

* Duffee’s KO (shown below) is recorded as the fastest ever in UFC history, but the un-official record belongs to Duane “bang” Ludwig.
