Heavyweight prospect Todd Duffee (6-0), who earned a UFC-record 7-second knockout of Tim Hague in August in his UFC debut, has been forced with withdraw from his UFC 107 matchup with a returning Paul Buentello due to an undisclosed injury.

Duffee confirmed the withdrawal on Tuesday with Sherdog, which also spoke to Buentello, who says Stefan Struve and Mike Russow have been proposed as potential opponents for the main card fight.
