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.

UFC heavyweight champion Brock Lesnar, who last week withdrew from his scheduled title defense against Shane Carwin at UFC 106 due to an extended illness, remains sick and unable to train, according to an update from Yahoo Sports’ Kevin Iole.

If Lesnar is unable to resume training soon, the Lesnar-Carwin matchup could be pushed back until February and UFC 108 could be left without a championship main event.
