Originally reported by the Boston Herald, Henderson and Alvarez will serve as the co-main event for the card at the TD Garden.
Henderson (21-4) was working his way back to a shot at the UFC lightweight title until he met Rafael dos Anjos last August. In the bout, dos Anjos knocked the former title holder out in the first round, giving Henderson his second loss in two years.
Alvarez (25-4) was the lightweight talk of 2013 when he was the center of a lawsuit that saw him try to sign with the UFC from Bellator. He ultimately fought for Bellator one more time, winning the promotion’s lightweight title back from Michael Chandler. Bellator then released Alvarez, allowing him to quickly sign with the UFC for a fight with Donald Cerrone, which the newcomer lost by unanimous decision.
