Alex Karalexis began competing in professional mixed martial arts in 2003, debuting with the Mass Destruction promotion, where he won his first four fights. He won two via TKO and the other two via decisions.
The Ultimate Fighter
Karalexis may best be known for his appearance on the first season of The Ultimate Fighter. He was a Middleweight contestant, where he was coached by former UFC Heavyweight and Light Heavyweight Champion Randy Couture.
At The Ultimate Fighter 1 Finale Karalexis fought Josh Rafferty, defeating him via TKO (Punches) in the first round. His next fight took place at UFC Ultimate Fight Night, losing to Kenny Florian. He lost his second fight in a row against Jason Von Flue in his next fight at UFC Ultimate Fight Night 3. This was his last fight with the UFC.
After winning one fight outside of the big shows, Karalexis re-emerged with Zuffa-owned World Extreme Cagefighting (WEC). His first bout was against journeyman Thomas Denny at WEC 23: Hot August Fights, winning a unanimous decision.
His second fight with the promotion pitted him against Olaf Alfonso, where this time he won due to doctor stoppage in the second round.
In Karalexis' next bout he made his Lightweight debut against Josh Smith, winning a majority decision.
His next fight was to take place on the main card of WEC 43: Cerrone vs. Henderson against Anthony Pettis, but Karalexis was forced off the card with an injury. Karalexis was once again expected to fight, but was forced off a card due to an injury. The fight was supposed to take place at WEC 44: Brown vs. Aldo on November 18, 2009 against WEC newcomer Kamal Shalorus.
Karalexis was first scheduled to return to face Zach Micklewright, but he was replaced by Anthony Pettis on the undercard of WEC 48: Aldo vs. Faber. Karalexis was dominated in the first round, where his opponent proved to be dominant in the standup or on the mat. Shortly after Karalexis opened the second with a double-leg takedown, Pettis threw his legs up for a Triangle Choke and forced a tappout at the 1:35 mark of the second frame.
Following the UFC/WEC merger in December 2010, Karalexis was released by Zuffa, LLC, having lost 3 of his last 4 WEC fights. He would return to action on June 10th, 2011 in a welterweight bout against Tiawan Howard at CES MMA VI: Nowhere To Hide, losing via split decision.
