Ivan Erslan Post-Fight Interview | UFC Fight Night: Allen vs Costa
/

The Croatian veteran came out firing heavy to start the contest, taking the fight to Tokkos, who weathered the storm and rallied back in the second half of an entertaining first round. Things slowed in the second, with Erslan landing the more telling blows before landing in top position and grinding out the clock before he was able to stuff a telegraphed takedown attempt early in the third, which allowed him to once again settle into top position and remain there for the duration.

All three judges scored the fight in favor of Erslan, who halted a three-fight slide with the win, advancing to 15-6 overall with the victory. This was a crucial performance from the 34-year-old, who took umbrage with some of what Tokkos said in the build to this contest and made him pay for his words.

The recent Dana White’s Contender Series grad controlled the opening stanza with his wrestling, staying stuck on his short-notice foe, repeatedly dragging him to the canvas and giving him no space. In the second, Gantt was able to keep Minev pinned to the canvas, and once that happened, the young Ukrainian began to break, allowing the North Carolina State product to turn up the pressure and output in order to earn the finish.

The Nova União representative was the more effective of the two in the opening round, landing the bigger blows before taking the fight to the canvas and roughing up Cavalcanti from top position. The Portuguese prospect was slightly more aggressive, pressing the action in the third, but it felt like a case of “too little, too late” for the ascending fighter.

When the scorecards were collected and totaled, it was Vieira that came out ahead. This was the Brazilian’s 10th UFC victory and another instance where the difference in experience and diversity of skill proved to be the deciding factor in a crucial and competitive fight.

Barez came out attacking, bringing the fight to the Dana White’s Contender Series grad, but Gurule dealt with the early pressure and responded in kind, taking it to his Spanish foe in the back half of the round. In the second, Gurule hurt Barez multiple times, moving forward without pause, continuing the approach in the third to distance himself from the steely veteran.

Gurule wasn’t able to find a finish, but the outcome was never in question when the final horn sounded. After landing on the wrong side of the result in each of his first three outings, breaking into the win column with a wildly entertaining performance like this had to feel good for the Colorado-based DWCS alum.

It was a gutsy effort from the Dana White’s Contender Series grad, who was fading in the third, but found another gear. As she gets more comfortable with the shift to 115 pounds, it will be interesting to see how Caliari progresses inside the Octagon.
