MMA veteran David Michaud’s career is in jeopardy after a diagnosis of congenital heart disease forced him to fight Rory MacDonald in the first round of the PFL welterweight tournament. ⠀ ud Michaud was scheduled to face MacDonald at PFL 2 on April 29. “Bulldawg” revealed the news of his withdrawal on Twitter, after doctors discovered congenital heart disease that could prove fatal if he were to fight again. ⠀ ⠀ ⠀ “So this will be a difficult article. After several tests on my heart, including a cardiac MRI and talking with several cardiologists, I was informed that I had a bad ticker, ”Michaud wrote. “I have a congenital bicuspid aortic valve with a dilated aortic root. ⠀ ⠀ Michaud told MMA Fighting that he became aware of the problem after abnormal EKG scans during his pre-fight checkup. ⠀ ⠀ “Unfortunately, I was born with this, because of the dilation of the aorta, the fighting exposes me to aortic dissection – a tear in the aorta,” Michaud continued. “It would be fatal in almost any circumstance. Because of this, I won’t be able to fight Rory Macdonald on April 29, and unless something changes, never again. ”⠀ ⠀ Michaud, 32, has been fighting for more than a decade, amassing an 18-6 record. He has fought for several different promotions during his career like the UFC, the Bellator and most recently the PFL. ⠀ ⠀ It’s unclear if MacDonald, who was set to make his PFL debut, will stay on the April 29 card.
