Rafael dos Anjos' title reign came to an abrupt end Thursday night as challenger Eddie Alvarez scored a first-round TKO in the main event of UFC Fight Night to walk away UFC lightweight champion.

Alvarez pushed a fast-and-furious pace, which dos Anjos matched, but was able to catch the Brazilian with a big straight right hand that sent his opponent stumbling backwards.

RDA survived for as long as he could, but Alvarez kept pouring it on until Herb Dean stepped in and called an end to the fight.

UFC fighters took to Twitter to react to the crowning of a new UFC champion.
