Larissa Pacheco vows to ruin Kayla Harrison’s perfect run under the Professional Fighters League banner with a knockout in December.

If fans are looking for a preview of coming attractions, Pacheco points them to her dominant decision over Sarah Kaufman in the PFL Season 2 semifinals.

”My hands are heavy – I know that,” Pacheco told MMA Fighting. “You all saw that in my last fight. Sarah is very tough, I respected her a lot, but Kayla can’t take what she took. She’s not used to it.

”People don’t get punched in the face in her sport, and she didn’t have to deal with that because she took her opponents to the ground and finished them too quickly.”
