All main-card fighters competing in Friday's Showtime-televised Strikeforce Challengers 9 event successfully made weight for the show.

Thursday's weigh-ins took place at Comcast Arena of Everett in Everett, Wash, which also hosts Friday's fight card.

Heavyweight headliners Shane Del Rosario (9-0 MMA, 1-0 SF) and Lolohea Mahe (4-1-1 MMA, 0-1 SF) had no problem making weight, and female champion Sarah Kaufman (11-0 MMA, 3-0 SF) and Roxanne Modafferi (15-5 MMA, 0-1 SF) also made their bout official by each weighing comfortably less than 135 pounds.

The favored main-eventer Del Rosario refused to discount his hard-hitting opponent.

"He's got a big hand and a tough chin," Del Rosario said. "It's going to be a hard fight, that's for sure. I’m going to keep my hands up and do my thing."

Meanwhile, in the title fight, the champion Kaufman said she hopes to earn a stoppage

"I'm happy fighting anywhere that I can let my hands go," Kaufman said. "It doesn't matter if it's on the ground or standing.

"I’m looking to knock her out. You always want to finish it."
