This marks Kennedy's second failed attempt at the Strikeforce 185-pound title. He lost a unanimous decision to Ronaldo (Jacare) Souza two years ago.
Nate Marquardt scored a huge knockout victory over Tyron Woodley to win the vacant Strikeforce welterweight championship in the co-main event.
Woodley dropped Marquardt early, but the former UFC middleweight title challenger returned the favour to steal the round. Marquardt continued to chip away in the second, landing a hard spinning back-kick and securing a takedown. Woodley bounced back in the third, hurting Marquardt and unloading with ground-and-pound, but the momentum was fleeting. In the fourth, Marquardt unloaded a brutal series of elbows and uppercuts to put away the former NCAA Division I wrestler.
“I tell you what, T-Wood is one tough dude,” Marquardt said. “He was a lot more game when I started catching him than I thought he would. He's a tough dude.”
Marquardt said he knew Woodley was done after the uppercuts and opted not to deliver ground strikes.
“He was out,” Marquardt said. “There was no need for more.
“T-Wood, keep your head up. When you have a family and kids like yo do, you're always a champion.”
Marquardt's previous outing saw him win a unanimous decision over Dan Miller at UFC 128 on March 19, 2011. He was set to face Rick Story at welterweight three months later, but was refused medical clearance on the day of the weigh-ins due to elevated testosterone levels from testosterone replacement therapy (TRT). UFC president Dana White immediately cut Marquardt from his contract.
The Strikeforce welterweight title was vacated when Nick Diaz jumped ship to the UFC last year.
Roger Gracie won a unanimous decision over Keith Jardine in his middleweight debut.
Gracie dominated Jardine throughout the first two rounds, taking the TUF 2 cast member to the ground and opening him up with a vicious elbow. Gracie then attempted to secure a submission, but couldn't lock one up due to the blood. Up two frames on the judges' scorecards, Gracie coasted through the third.
“I'm very happy,” Gracie said. “I was able to do my game plan, but at one point he was too slippery.
“The third round I got quite tired and used my reach to keep him away. I was very happy at this weight, but I think the reason I got tired is I left the weight cut to the last minute.”
Jardine is now 2-7-1 in his last 10 fights.
Lorenz Larkin also made a successful middleweight debut, out-striking Robbie Lawler en route to an exciting unanimous decision.
Lawler hurt Larkin early with a left-hook to the temple, but the Kung Fu practitioner recovered and took the fight to the UFC veteran. In the second round, Larkin busted open Lawler's head with a nasty high kick and continued to stay busy with combos to snag all three rounds.
“Robbie hit me with a punch that made me do the stinky leg, but I worked through it,” Larkin said. “I stood up with Strikeforce's deadliest striker and went all three rounds.”
Following the bout, Larkin pleaded with UFC president Dana White to establish night bonuses for Strikeforce competitors.
Pat Healy won a debatable unanimous decision over Mizuto Hirota in the final preliminary bout. Healy is now riding a five-fight win streak and may have earned the right to challenge Strikeforce lightweight champion Gilbert Melendez.
Ryan Couture snagged a hard-fought split decision over Joe Duarte.
Jorge Masvidal won a close split decision over Justin Wilcox.
Jordan Mein got back in the win column, defeating Tyler Stinson via unanimous decision.
The Lethbridge, Alta. welterweight lost a tough split decision to Woodley in his last outing. He has now won eight of his last 10 bouts.
The opening bout saw Jason High submit Nate Moore with a guillotine choke in only 26 seconds.
