Tompkins, who coached the Los Angeles Anacondas in the International Fight League (IFL), is 0-4 in his MMA career and has not fought since 2001.

Shamrock (26-13-2) has lost his last four straight bouts and six of his last seven. He was last in action in March, losing to Robert “Buzz” Berry via first-round knockout at Cage Rage 25.
