The latest installment of Dana White's Contender Series showcased thrilling performances, highlighted by Adam Darby's impressive third-round stoppage of Patrick Rivera at the UFC Apex in Las Vegas.

Darby, the reigning Cage Warriors welterweight champion, effectively utilized his 6-foot-3 frame to keep Rivera at a distance from the start. His strategy involved long, straight punches and kicks, stifling Rivera's attempts to gain any momentum. By the end of the second round, Rivera's face was bloodied, and it appeared his best chance was merely surviving until the final bell.

However, Darby continued to press his advantage, landing significant shots that led to the fight being stopped after the referee called in a doctor to evaluate Rivera. With this victory, Darby improved his professional record to 8-1, marking his first fight on American soil as he aims to join the UFC welterweight roster.

In the co-main event, Modestino Rodrigues delivered a stunning performance, dropping Brandon Holmes with a right hand just 15 seconds into the fight. Despite UFC CEO Dana White labeling the stoppage as one of the worst he had seen, he acknowledged it was not Rodrigues' fault and awarded him a UFC contract, bringing his record to 8-1, with all nine of his fights ending in knockout.

Additionally, Silvestre Sanchez triumphed in a grueling lightweight clash against Liam McCraken, ultimately finishing him with a left hook in Round 3. Gabriel Lorenco, an underdog at +185, also made waves by stopping Charlie Cleveland with a powerful punch in Round 1.
