Caol Uno

Uno fought Jesse Brock at Vale Tudo Japan: VTJ 4th, on February 23, 2014. He won via unanimous decision.

On March 31, 2010, Uno fought Gleison Tibau at UFC Fight Night 21. He was overpowered by the much bigger Tibau, and suffered a loss via TKO (punches). After the fight he was released from the promotion.

Uno was spotted in attendance at UFC 94, fueling talk of a return to the UFC's Lightweight division. It was later confirmed that Uno had signed with the UFC and would face Spencer Fisher at UFC 99: The Comeback. In spite of finishing the bout pounding Fisher with punches from top crucifix position, Uno lost by a controversial unanimous decision. Then, on November 21, 2009, Uno fought UFC newcomer Fabrício Camões to a majority draw at UFC 106.

Uno next competed in DREAM's Lightweight Grand Prix. He was seeded directly into the second round, DREAM 3, where he beat Mitsuhiro Ishida via rear-naked choke submission to progress to the Dream 5: Lightweight Grand Prix 2008 Final Round. At Dream 5, Uno lost a unanimous decision to Shinya Aoki.

Uno then went on to fight Tatsuya Kawajiri in Shooto before fighting at K-1's 2004 Premium Dynamite!! and K-1 MAX: Japan Grand Prix 2005. His next eleven fights were for the then newly established promotion Hero's.

He returned to AJPW in May 2003 under his Apeman Nigo persona. He and Kaz Hayashi lost to Kashin and Low Ki, but at the next event he teamed up with Ki to beat Gran Naniwa and Ryuji Hijikata. At the next day, he competed under his true name with Keiji Mutoh, winning over 728% Machine and The Apeman 200%, and then recovered his Nigo mask to team with Mutoh and Taka Michinoku in a winning effort against The Great Sasuke, The Great Kosuke and The Apeman. Uno's last appearance for AJPW would be in July, allying with Kashin and Robbie Brookside to beat Hayashi, Jimmy Yang and Ebessan.

Uno then signed up with All Japan Pro Wrestling in June 2002, where he debuted as a partner for Kendo Kashin against Kaz Hayashi and Kashin's double Mr. Problem (played again by Matsui), albeit in another losing effort. In November, he became also part of the event Wrestle-1, co-promoted with K-1. Coming under a monkey mask (which he quickly lost) and the name "The Apeman Nigo", Uno teamed up with Kashin to defeat La Parka and Super Parka.

The two rematched in December 2000. This fight concluded with Uno standing over Sato on his back, then striking him with a knee and a punch while he was getting up, knocking him out.

Uno debuted in professional wrestling in December 2000 as part of the Inoki Bom-Ba-Ye event. He teamed up with Akira Shoji against The Great Sasuke and Daijiro Matsui, but his team lost when Sasuke pinned him.

Uno rose through the ranks of the Shooto mixed martial arts organization in Japan. In May 1999, Uno fought the then-legendary Rumina Sato. The fight was hailed as "Fight of the Year", an extremely fast-paced back and forth battle with a wide variety of stand-up and grappling exchanges. Eventually, Uno took the back of Sato and choked him into submission.

Uno finished second in the All Japan amateur Shooto tournament in 1996. He was a runner-up in the submission wrestling world championships at ADCC losing in the finals to world-renowned Jean Jacques Machado.

Kaoru "Caol" Uno (宇野薫 , Uno Kaoru) (born May 8, 1975) is a Japanese mixed martial artist and professional wrestler. He is the Co-Champion of the UFC 41 Lightweight Tournament and a former Shooto Lightweight Champion. As one of the early Ultimate Fighting Championship's elite Lightweight competitors, Uno competed for the UFC Lightweight Championship on two separate occasions. Despite falling short in both championship bouts; losing a five-round decision against Jens Pulver at UFC 30, to determine the inaugural UFC Lightweight Champion as well as a draw against B.J. Penn at UFC 41 (in a bout which would have determined the new UFC Lightweight Champion and UFC 41 Lightweight Tournament Winner), Uno is acknowledged as a pioneer for his impact and influence during the early era of the UFC Lightweight Division.
