Anthony Pettis will begin his hunt to reclaim the UFC’s lightweight title this Sunday at UFC Fight Night 81, when he takes on Eddie Alvarez. The bout will mark the first time “Showtime” has fought since last March, when he lost the title to Rafael dos Anjos, in what was his second title defense.

In advance of this weekend’s bout, the UFC has posted the fighter’s biggest win to date–when he submitted Benson Henderson to secure the lightweight championship. It was an impressive win for Pettis, particularly when you consider that he tapped out a noted grappler and BJJ black belt.
