Kerr will be taking on Penner, a 29-year-old who has fought mostly locally in Alberta, Canada. In his second pro fight, Penner scored a first round submission via strikes victory over Butterbean. His lone loss was against Jimmy Ambriz via unanimous decision.
Kerr will always be remembered for his early UFC tournament wins, at UFC 14 and 15, as well as his dominance in the early PRIDEs, but since 2000, he has lost ten of 14 fights.
Kerr's battle with painkiller addiction was well documented in the HBO documentary "The Smashing Machine: The Life and Times of Extreme Fighter Mark Kerr" in 2003. After the release of the film, he fought once more for PRIDE and then began his current comeback in November 2006 for the IFL.
"Capital Excalibur" will be headlined by a welterweight bout between Shannon Ritch and Jose "Pele" Landi-Jons.
