Jack Hermansson has proven time and time again just how dangerous he is on the mat. Coming off the biggest win of his career over Thales Leites, Hermansson faced Gerald Meerschaert at UFC on FOX 31 in December 2018. His grappling was put to the test against jiu-jitsu blackbelt Meerschaert, but it took Hermansson less than 20 seconds to get the fight to the mat and immediately establish full mount. Meerschaert hung tough, but Hermansson dominated all positions in the grappling exchanges, eventually sinking in a guillotine choke and submitting Meerschaert right before the end of Round 1. Hermansson returns to action Saturday against Marvin Vettori (15-3-1 MMA, 5-2-1 UFC) in the main event of UFC on ESPN 19, which takes place at the UFC Apex in Las Vegas.
