Isaiah Abels, an MMA fighter, experienced a cardiac arrest during his match last weekend.
On Saturday night in Evansville, Indiana, the 21-year-old faced Saevon Canto.
The American suffered a cardiac arrest shortly after completing a takedown in the second round.
After some initial confusion, medical professionals rushed into the cage to treat Abels right away.
He was stabilised in the hospital an hour later, but according to MyMMANews, he was still there as of Monday.
Last Sunday, Abels’ brother Zach wrote on Facebook, “Last night, Isaiah Abels engaged in combat. It was contested twice. He won the opening round with some lovely striking.
“The fight transitioned into the second round. Isaiah continued to pick his shots and maintained his pace and distance.
“Unexpectedly he was countered with a lead hook. He responded with a takedown and continued to pressure his opponent against the fence to recover from the hook.
“Isaiah then disengaged from the clinch and went to press forward. As he continued to pressure his opponent something ominous happened.
“Isaiah took a step forward and collapsed to his knees. He was going into respiratory arrest. Soon after the fight was stopped. The ref had no idea what really happened thinking it was a typical stoppage.
“Clearly it wasn’t. Isaiah wasn’t getting up because he was also going into cardiac arrest.
“Once the doctors and medics accessed the situation. They got his heart going as they assisted his breathing. We rushed to the hospital. A hour or so later Isaiah was stabilized.
“I don’t know what you believe in, but the fear of God was put into all of us last night. Words can’t even describe.
“I’m grateful for everyone praying and thinking about him, but I really wanna thank the medical professionals along with God.
“Again, I don’t know to what degree you believe in God, but please continue to keep Isaiah in your thoughts and prayers. Please, God. Please everyone. Please. I love you, Isaiah Lee.”
A statement from the Southern Indiana Combat Production, who staged the fight and subsequently cancelled the rest of the night’s scheduled bouts, read: “We thank everyone for showing your support through this whole situation.
