Galvao (17-6-1) won the Bellator MMA bantamweight title Friday night, submitting Warren via kneebar at the 45-second mark of the second round. The title fight headlined Bellator 135 at Winstar World Casino and Resort in Thackerville, Oklahoma.
The Brazilian jiu-jitsu black belt caught Warren in the kneebar early in the second round. Warren attempted to gut out the hold, but as Galvao rocked violently back and forth, he couldn't suppress a scream. Referee John McCarthy immediately stopped the fight, awarding Galvao the first submission win of his career.
Warren (12-4), a two-division Bellator champion, immediately protested the stoppage to no avail.
"He had a good move, but come on, give me a break," Warren said. "That was not a submission. You guys all saw that. I'm the baddest man on the planet and that's my belt."
Galvao, who suffered a controversial decision loss to Warren in 2011, said, "I respect Joe Warren. He's a nice guy. He talks because he promotes fights. But today, (he verbally tapped)."
The fight was fairly even to that point. Warren executed his style well in the opening frame, smothering Galvao in takedown attempts along the fence, landing decent knees to his legs in the process. He scored his first takedown of the fight within the first 40 seconds and landed a hard right hand during one exchange on the feet.
Galvao appeared comfortable handling Warren's pressure, however, and responded with offense of his own. Near the end of the first round, he tagged Warren with a right hand and followed it with a hard knee to the body.
The victory completes a long road for the 33-year-old Brazilian, who has an overall Bellator record of 8-3. In 2012, Galvao won the Bellator Season 6 bantamweight tournament, which ultimately set him up with a title shot against his former Nova Uniao teammate Eduardo Dantas. Galvao suffered a brutal knockout loss in the second round.
Warren, 38, suffered his first loss since March 2012. He won the interim bantamweight title in a unanimous decision victory over Rafael Silva last May before unifying the two belts in a decision over Dantas in October. ESPN.com ranked Warren the No. 8 bantamweight in the world heading into his first title defense.
Davis earns narrow victory in co-headliner
Davis (23-6) squeaked out a split-decision win over the Japanese veteran despite nearly being finished multiple times in the third round. Two judges scored the 135-pound contest 29-28 for Davis, while a third had it for Tokoro (32-28-2), 29-28. ESPN.com scored it for Davis, 29-28.
With a mouth full of blood, Davis dedicated the win to his family, including his late brother, Ryan Cobbins, who was murdered in late 2013.
"Man, every round was tough," Davis said. "Hats off to that guy. [Tokoro's] a veteran and it was an honor to fight him. I was here to win. First round, second round, third round, I was looking for the knockout."
A former collegiate wrestler, Davis had no issues letting his hands go on Friday. He narrowly outpointed Tokoro in the first round, finding a frequent home for his straight left hand. The round was close, however, as Tokoro hurt Davis with a right late.
In the second round, Tokoro made a tactical error, as he jumped into a flying knee attempt, but altered midair into a halfhearted punch. Davis countered with a stiff right that dropped his opponent in the center of the cage. He followed him to the floor, where was forced to fight off several leglock attempts.
The best action was reserved for the final frame, as Tokoro came out guns blazing from the opening bell. He stiffened Davis with a short left hook, then dropped him with a right. Winner of 18 fights by submission, Tokoro stepped immediately into an armbar attempt, but Davis escaped. Tokoro was called for an illegal upkick moments later, although replays showed the strike was legal.
The rest of the round featured wild scrambles, as each fighter refused to hold back on submission attempts. In a fitting end, time expired as Davis attempted to put a final squeeze on a guillotine choke.
A former highly ranked WEC featherweight, Davis, 34, improves his Bellator record to 3-0. He has now won seven of eight bouts, since dropping to the bantamweight division.
Carmont wins Bellator debut
The former UFC middleweight was forced to fight off several rear-naked attempts in the final round, but took home a clear decision win. All three judges scored the fight 29-28 for Carmont (23-10).
Fighting out of Tristar Gym in Montreal, Carmont racked up points in the first and second rounds with inside leg kicks. He showcased an accurate jab as well, but it was the constant leg kicks that had a visible effect on Viana (6-2), who suffered his first defeat since December 2012.
Carmont did struggle to get the fight to the ground as often as he wanted, but Viana failed to make him pay for any busted efforts. In the second round, Carmont hurt Viana with a right cross to the temple. As Viana staggered around the perimeter of the cage, Carmont hit him with a knee to the body and then a takedown, which nearly led to a rear-naked choke.
Knowing he was behind on the scorecards, Viana went for broke in the third. He hit Carmont with two left hooks that got his attention and worked a great sweep from off his back after forfeiting a takedown. Following the sweep, Viana took Carmont's back but did not look extremely comfortable looking for a finish. Carmont turned into him and spend the final minute of the fight on top.
The win snaps a three-fight losing streak for Carmont, who just two years ago was closing in on UFC title contention.
Couture cruises to fourth consecutive win
Couture (10-3) netted the sixth submission win of his career against Cochrane (18-8), securing a rear-naked choke at 3:23 of the first round. It is the sixth time Cochrane has lost via submission.
After defending early takedown attempts from Couture, Cochrane turned the tables on his grappling-heavy opponent, scoring a single-leg of his own in the opening minute. Couture, 32, rose quickly to his feet, at which point many would have figured Cochrane would back up and reset.
Instead, Cochrane shot on a double leg, which Couture sprawled on. Cochrane eventually fell to his knees, where Couture quickly moved to his back and sank his hooks in.
It was a pretty effortless finish from there for Couture, son of former UFC champion Randy Couture. He softened up Cochrane with punches to the head before slipping his right arm under the chin.
"As soon as I get that first hook, especially if I have the wrist on the other side, I'm a nightmare to get off," Couture said. "I give guys fits in the training room. Once I was there, I was confident."
Couture extends his win streak to four. He is 2-0 in the Bellator cage. Cochrane, 28, falls to 1-3 in his last four fights.
