choadler -Only saying this because I work in the field, but didn't struve have a cardiac ablation done? I wonder if that could have well been the anxiety attack that was mentioned previously. That type of cardiac problem often gets passed off (incorrectly) as an anxiety attack.
It was supposed to be his first fight back from treatment. From wikipedia:
On August 20, 2013, Struve was reported to have suffered from a leaking aortic valve as well as an enlarged heart, doctors found that Stefan has a bicuspid aortic valve, which means that his aortic valve only has two leaflets, instead of three. It was decided to treat his condition with medication for the next two months. On October 8, 2013, reports came that Struve's heart condition was improving and that a return to fighting was still a possibility. November 24, 2013, it was reported that he was ready to return to a full training schedule.
On April 7, 2014, manager Lex McMahon announced in the show "The MMA Hour" that Struve has approval from the doctor to fight again and return to the Octagon. Quote: “I think we’re very close. Very exciting news with Stefan, he was actually cleared by his doctor in the Netherlands. Right now we’re just waiting for a copy of his file to be translated so that the UFC can have their doctor take a look at it, and they’re going to determine whether or not to have Stefan get a second opinion or not. If they do bring him out for a second opinion, that would likely be out in Los Angeles with the UFC’s cardiologist that they use frequently. I believe they sent Dan Hardy to him and a few other folks.”
Struve was expected to face Matt Mitrione on July 5, 2014, at UFC 175. During the first fight of the main card, however, Struve fainted in the dressing room and had an elevated heart rate. UFC personnel decided to cancel the fight. Struve was later taken to the hospital for precautionary reasons.
