Ismael Bonfim is a Brazilian mixed martial artist who competes in the lightweight division. He has a professional record of 15 wins and 3 losses, with 10 of his wins coming by way of knockout. Bonfim has competed in various organizations such as LFA, Titan FC, and Brave CF, but has yet to make his UFC debut.

Terrance McKinney, on the other hand, is an American mixed martial artist who also competes in the lightweight division. He has a professional record of 11 wins and 3 losses, with 7 of his wins coming by way of knockout. McKinney made his UFC debut in June 2021 with a stunning knockout victory over Matt Frevola in just 7 seconds, which earned him a Performance of the Night bonus.

Both fighters have shown impressive striking skills and knockout power in their fights, and a matchup between them could be an exciting one to watch if it were to happen in the future. However, as mentioned earlier, there is no official announcement or confirmation of such a matchup taking place at UFC 283 or any other event.
