Kayla Harrison is aware that her cut to bantamweight is going to take some work.
Harrison (16-1 MMA, 0-0 UFC) makes her 135-pound debut against former champion Holly Holm (15-6 MMA, 8-6 UFC) on April 13 at UFC 300 in Las Vegas.
Two-time PFL winner Harrison has predominantly competed at lightweight throughout her career, but dismissed the notion that she competed with a big size advantage. But cutting down to bantamweight will give her that.
