Castillo vs. Lentz the latest addition to UFC on FOX 17

Danny Castillo will welcome Nik Lentz back to the lightweight division when the two meet in the Octagon at UFC on FOX 17.

After six bouts at featherweight, Lentz is moving back up to the 155-pound division, where "The Carny" compiled a 5-2-1 record from 2009 to 2012. In his last trip to the cage, at UFC Fight Night 67, Lentz was submitted by Charles Oliveira in a bout that earned him a $50,000 "Fight of the Night" bonus.

Currently embroiled in a three-fight losing streak, this could be a pink slip derby for Castillo. The 36-year-old Team Alpha Male product dropped a split decision to the leather-tough Jim Miller in his last outing at UFC on FOX 16 in July.

UFC on FOX 17 takes place at the Amway Center in Orlando, Fla., and features a lightweight title bout between Rafael dos Anjos and Donald Cerrone as the main event.
