Isaac was competing at a suburban MMA fight in Chicago.

The entire mixed martial arts industry can't revolve around the UFC. Some communities develop their own promotions, such as Joe Goytia's enterprise. The promoter was in charge of the event after which Isaac lost his life.

Joe explained to The Athletic: "In the back of your mind, you know this is a tough sport, you know injuries do happen in sports. But you never think this would happen. I know all the protocols were followed correctly, but in this case, it didn’t work.”

Even fighters such as Conor McGregor and Anderson Silva are always at risk of one wrong move bringing fatal consequences. Isaac's death served as a reminder of how dangerous mixed martial arts are, regardless of the level of competition dealt with.

Isaac will be remembered by those who knew him well. Besides his love for mixed martial arts, Isaac spent his time as a DJ and a creative entrepreneur, per his Instagram.

Isaac remains a valued member of his community. Those left with access to his Instagram account posted a touching tribute to the creative, highlighting how he enjoyed taking on challenges across different disciplines.
