Junior dos Santos defeated Derrick Lewis by TKO in the second round of their heavyweight bout Saturday night in the main event of UFC Fight Night at Wichita, Kansas.
Dos Santos hurt Lewis with a kick to the stomach late in the first round, causing Lewis to double over and grimace in pain.
Lewis appeared to recover by the second round, but Dos Santos rocked him again with a hard right hand midway through the round. With Lewis falling to the canvas, Dos Santos went in for the finish with a series of blows, before the referee stopped the bout at 1 minute, 58 seconds.
