MMAWeekly.com has learned that Mike Kyle has been suspended by the WEC until further notice.

Many fans of mixed martial arts have referred to Kyle as the dirtiest fighter in the sport on various MMA message boards, and what happened this past weekend will only add to the negative perception of Kyle that many people already had.

Last Friday, during his fight against Brian Olsen in the main event of the WEC show in Lemoore, California, Kyle illegally kicked Olsen in the head.

Kicking a downed opponent in the head is illegal in virtually every MMA promotion in the United States, including the WEC. Olsen was on the ground when he was knocked out by Kyle’s illegal kick to the head.

Making the situation even worse is the fact that Kyle then pounced on Olsen, delivering several punches to his unconscious opponent’s head. Referee Josh Rosenthal tried to position himself between the two fighters and stop Kyle, as fellow referee Herb Dean entered the cage to assist Rosenthal in preventing Kyle from continuing his assault on the unconscious Olsen. Olsen suffered a broken nose, and may have also suffered a broken cheek bone.

Herb Dean tells MMAWeekly, “They were in a scramble and Mike gets to his feet first, throws a kick, and catches the guy in the face with the kick, and when Josh [Rosenthal] went in to stop the fight, [Kyle] continued to punch the guy… it was an illegal kick. His opponent was grounded. He kicked him very hard.”

Dean continued, “[Kyle] was in control of the fight, and he probably would have won the fight. I mean, you never know, but he was winning the fight. He did continue to punch the guy. Josh came in to stop the fight, and the way they were angled against the fence Josh wasn’t able to get in there good enough to keep him from being able to reach the guy still, so I came over to help him stop the fight.”

WEC President Scott Adams tells MMAWeekly, “I have talked to his [Kyle’s] manager and told him that we have to suspend him indefinitely. That kind of behavior is not tolerated in MMA, and we had to do something about it, so we are suspending him now.”

MMAWeekly.com has also learned that Olsen is thinking about taking the additional step of submitting tape to the California State Athletic Commission for further review. Even if Olsen doesn’t take that measure on his own, the CSAC could request tape of the incident from the WEC.

Mike Kyle’s mixed martial arts career has been plagued by fouls and questionable in-fight behavior.

During his fight against Wes Sims at UFC 47 in April of 2004, Kyle allegedly bit Sims on the chest. The bite marks were visible on Sims’ chest during the post-fight press conference, which took place a few hours after Kyle’s bout that evening.

When Kyle fought Justin Eilers at UFC 49 in August of 2004, Kyle delivered knees to Eilers’ crotch on a few different occasions before time was called and Eilers was allowed to recover. Eilers came back and won the fight by knockout.

Kyle’s fight against Tsuyoshi Kosaka in the Pancrase organization in October of 2005 had to be stopped prematurely after Kosaka was poked in the eye. The fight was taken to the judges’ scorecards, where Kyle won unanimously.

When Kyle fought Krzysztof Soszynski on the undercard of the StrikeForce promotion’s “Shamrock vs. Gracie” card in March of 2006, the bout was ruled a technical draw after Kyle poked Soszynski in the eye approximately two minutes into the fight.

The accumulation of these incidents is very troubling, but the most outrageous incident by far took place last Friday night (May 5th) at the WEC show in Lemoore, California when Kyle knocked out his opponent, Brian Olsen, with an illegal blow and then refused to stop pounding on his unconscious opponent.

In addition to being suspended indefinitely by the WEC, it now appears that the California State Athletic Commission and the head of CSAC, Armando Garcia, could be looking into the latest Kyle incident.
