Knockouts by knee are the trending result at the season finale of Dana White’s Contender Series.

In the second bout of Dana White’s Contender Series 66 at the UFC Apex in Las Vegas, Marquel Mederos (8-1) became the second fighter in as many bouts to finish a fight with a knee knockout.

In the first round against Issa Isakov (10-3), Mederos pressed forward and timed a crushing knee to the jaw. Isakov was immediately stiffened and timbered to the canvas at 4:09.
