Fact Check: World Series of Fighting 29

Justin Gaethje has grown to appreciate the view from the top.

The unbeaten Gaethje will defend his World Series of Fighting lightweight championship against Brian Foster in the WSOF 29 headliner on Saturday at the Bank of Colorado Arena in Greeley, Colorado. The event will air live on the NBC Sports Network at 10 p.m. ET/7 p.m. PT.

Gaethje last appeared at WSOF 23 on Sept. 18, when he stopped Luis Palomino with second-round punches to punctuate their memorable two-fight series. The 27-year-old Grudge Training Center rep has secured 13 of his 15 career victories by knockout, technical knockout or submission and owns a perfect 8-0 mark in World Series of Fighting competition. Wins over Melvin Guillard, Nick Newell, Dan Lauzon and Gesias Cavalcante anchor the Gaethje resume.

Foster won an eight-man lightweight tournament on Nov. 20 to land his shot at the 155-pound title. The onetime Victory Fighting Championship titleholder boasts 24 finishes -- 12 by submission and 12 by knockout or technical knockout -- among his 25 professional wins, including five-, 32-, 59-, 67-, 69- and 90-second stoppages. Foster, 31, has gone 9-3 since being released by the Ultimate Fighting Championship following a November 2010 guillotine choke submission on Matt Brown.
