Magomedov (16-1-0) is making his Bellator debut in this bout and does so on the strength of a three fight winning streak. Magomedov is also competing for the first time in over two years, with his last bout happening in November of 2018. Magomedov has suffered a single defeat as a professional MMA fighter and that came to UFC veteran Petr Yan.
Mattos (12-1-1) is also making his Bellator debut in this bout and the fighter is also competing for the first time in two years. Mattos has suffered just one loss as a professional MMA fighter and much like Magomedov, that loss came to the aforementioned Yan. Mattos has competed 14 times as a professional MMA fighter and just three of them went the distance.
