Colin Matthew Delaney (born September 7, 1986) is an American professional wrestler best known for working with World Wrestling Entertainment (WWE) on its ECW brand. He has also wrestled for promotions such as CHIKARA, NWA Upstate, Buffalo Championship Wrestling, NWA Empire, Pro Wrestling Ohio, UWA Hardcore Wrestling, Roc City Wrestling, and Combat Zone Wrestling under the name Colin Olsen.
Wrestling as Colin Olsen, Delaney has won wrestling championships. For his 1st championship, he teamed with his kayfabe brother Jimmy to win the NWA Upstate Tag Team Championship on November 13, 2004 by defeating the Ring Crew Express (Kevin Dunn and Mean Marcos). They held the belts for over six months before dropping them to The Outcast Killaz on May 14, 2005. They also captured the RCW Tag Team Championship on January 20, 2006 defeating the Prophets of Pain (Father Synne and Hard Knox) and retained until June 9th 2006 when they were stripped of the titles after a working arrangement between NWA Upstate and Roc City Wrestling was dissolved.
On May 19, 2007, Olsen defeated "Mastiff" Will Christianson and Damien Alexander to win NWA Empire's Lord of the Dance Championship, a title which can only be contested in three-way matches.
On June 7th, 2007 Colin & Jimmy Olsen wrestled for Action Packed Wrestling in Rutland, Vermont in a 3-Way Scramble Match against Dunn & Marcos and Rhythm & Booze.
Colin's last defense of the NWA Empire's Lord of the Dance Championship was at on December 8, 2007 where he wrestled his kayfabe brother Jimmy Olsen and "Mastiff" Will Christianson. At an NWA Empire show on February 9, 2008, Delaney vacated the title due to his ECW brand commitments.
Delaney picked up his first win in WWE on the February 26, 2008 edition of ECW, defeating The Miz and John Morrison in a tag team match with Tommy Dreamer. On March 11, he and Dreamer challenged The Miz and Morrison for the WWE Tag Team Championships in an Extreme Rules match, but came up short after having lost a subsequent title match the week before. In subsequent weeks, ECW General Manager Armando Estrada informed Colin that he would have to acquire his first singles victory to win an "official" ECW contract. Delaney unsuccessfully faced a number of superstars, including his own mentor Dreamer, whom Estrada threatened to fire if he lost the match. Finally, on the May 6, 2008 edition of ECW, Delaney defeated Estrada himself via a sunset flip to win his storyline contract, which he had legitimately signed in February. He lost his "first match as an ECW superstar" against Mike Knox and then was beaten by Estrada when he signed himself to the ECW roster. In a bizarre twist of fate, Estrada was defeated by Delaney after already being defeated by Matt Hardy moments earlier, thus removing Estrada from the roster, per the orders of new ECW General Manager Theodore Long. On July 20, 2008, at The Great American Bash, Delaney turned heel by costing Tommy Dreamer his ECW Championship match against Mark Henry On July 29, however, on ECW, he lost to Matt Hardy, which caused Henry to turn on him. The next week on ECW, Delaney helped Estrada beat Dreamer to earn his ECW contract. This led to an Extreme Rules match against Dreamer, where he was easily defeated. On August 15, Delaney was released from his WWE contract.
