UFC 22: Only One Can be Champion

UFC 22: Only One Can be Champion was a mixed martial arts event held by the Ultimate Fighting Championship on September 24, 1999 at the Lake Charles Civic Center in Lake Charles, Louisiana.

The event was headlined by a Middleweight Championship bout between Frank Shamrock and Tito Ortiz, and also featured two preliminary bouts, a middleweight bout, two heavyweight bouts, and two lightweight bouts. The Ortiz-Shamrock fight was notable for being widely considered one of the best MMA fights ever at the time it took place, due to the complete range of skills showed by both fighters. The bout featured back-and-forth action which saw multiple takedowns from Ortiz and crisp kickboxing displayed by Shamrock, who eventually forced Ortiz into submission with brutal punches, elbows, and hammerfists to the temple late in the 4th round.

UFC 22 marked the first UFC appearance of future UFC Welterweight Champion Matt Hughes, who would go on to dominate the UFC's Welterweight division (which at the time was called "lightweight", until the UFC was sanctioned in 2001, when official weight classes were introduced), as well as Jens Pulver, who fought in a preliminary bout that was not televised. It also was the last UFC event that Frank Shamrock ever fought in.

UFC 22 was the last UFC event by SEG to see a home video release, as SEG was nearing bankruptcy and struggling to keep the UFC alive through extremely limited pay per view in the US, as well as minor coverage in Brazil and Japan. UFC 23 through UFC 29 were never released in the US on home video or DVD in any form, and many consider this period to be the "Dark Ages" of the UFC. It wasn't until UFC 30, with new owners Zuffa, that the UFC returned to home video.
