The climb up the Ultimate Fighting Championship lightweight division has grown increasingly steep for Mark O. Madsen.

Madsen will put his perfect 11-0 record on the line when he meets “The Ultimate Fighter” Season 15 semifinalist Vinc Pichel as part of the UFC 273 undercard on April 9 at the VyStar Veterans Memorial Arena in Jacksonville, Florida. The undefeated Dane has turned away three opponents inside the Octagon since he joined the UFC roster in 2019. Madsen last fought at UFC on ESPN 29, where he eked out a split decision over former Strikeforce champion Clay Guida on Aug. 21. Pichel, meanwhile, enters the cage on the strength of a three-fight winning streak. The Factory X export has not tasted defeat since he submitted to a Gregor Gillespie arm-triangle choke at UFC Fight Night 131 on June 1, 2018.

As Madsen and Pichel move ever closer to their three-round confrontation at 155 pounds, a look at some of the numbers that have accompanied them to this point:

37: Years of age for Madsen, who was born on Sept. 23, 1984 in Nykobing Falster, Denmark.
