Earlier this week, a long-awaited bantamweight title defense for TJ Dillashaw — a meeting with former titlist Dominick Cruz — was announced for a UFC Fight Night event, scheduled for Boston on January 17.

Now, it looks like that championship fight will be accompanied by another bout between two of biggest stars among the lighter weight divisions: Eddie Alvarez and Anthony Pettis (pictured above).

Alvarez, the current UFC lightweight contender and former champ for Bellator MMA, broke the news on his Twitter account:

Alvarez and Pettis are currently ranked the #1 and #4 contenders, respectively, to UFC lightweight champion Rafael Dos Anjos.

Pettis, who is 18-3 in MMA (5-2 in UFC), will be looking to regain some lost momentum with the bout. From 2011 to 2014, the Milwaukee, WI native enjoyed a five fight win streak, including a victory over Ben Henderson to gain the UFC lightweight title. He was one of the UFC’s glamor boys, complete with a spot on the cover of Wheaties breakfast cereal. But all that changed in March when he lost his title via a lopsided decision against Dos Anjos.

Philadelphia’s Alvarez is 26-4 in MMA (1-1 in UFC). Back in June, he rebounded from a disappointing unanimous decision loss to perennial contender Donald “Cowboy” Cerrone in his UFC debut, to defeat Gilbert Melendez via split decision. He exited Bellator on an impressive win streak; having defeated Michael Chandler, Shinya Aoki, and Patricky “Pitbull” in successive bouts.

UFC Fight Night Boston, aka UFC Fight Night 81, is scheduled to air on Fox Sports 1 in North America.
