UFC heavyweight champion Brock Lesnar has withdrawn from his UFC 106 main event title defense against unbeaten Shane Carwin due to an illness that has forced him out of training camp for nearly a month. The UFC hopes to re-schedule the bout for early 2010. Stepping up into the main event slot will be the highly-anticipated rematch between former light heavyweight champions Tito Ortiz and Forrest Griffin.
Tickets are on sale now for UFC 106: Ortiz vs Griffin 2, which takes place at the Mandalay Bay Events Center in Las Vegas, Nevada.
