Weigh-ins for Friday's "Strikeforce Challengers 9: Del Rosario vs. Mahe" event are scheduled for Thursday at Comcast Arena of Everett in Everett, Wash.
The event, which begins at 7 p.m. PT local time (10 p.m. ET), is free and open to the public.
The same venue also hosts Friday's fight card, which airs on Showtime.
"Strikeforce Challengers 9: Del Rosario vs. Mahe" features a main event between heavyweight prospects Shane Del Rosario (9-0 MMA, 1-0 SF) and Lolohea Mahe (4-1-1 MMA, 0-1 SF).
Del Rosario, an EliteXC and M-1 Challenge vet, made his Strikeforce debut this past November and scored a submission win via the rarely seen omoplata lock over Brandon Cash. The fast-rising prospect is 9-0 with nine stoppages, and eight have come in the first round (seven via knockout).
Mahe also recently made his Strikeforce debut. In the main event of a March Challengers event, Mahe suffered a second-round TKO loss to Lavar Johnson. Prior to the promotional debut, he went undefeated on the Hawaiian fight circuit, which included a draw with UFC vet Scott Junk at a February 2009 X-1 event.
In other main-card action, Strikeforce women's welterweight champion Sarah Kaufman (11-0 MMA, 3-0 SF) defends her belt against Roxanne Modafferi (15-5 MMA, 0-1 SF).
Kaufman, who makes her fourth-straight Challengers appearance, has not fought since her unanimous-decision win over Takayo Hashi in February. The victory earned the Canadian fighter the first-ever Strikeforce women's welterweight belt and extended her undefeated streak to 11 fights.
Although Kaufman opened her career with eight consecutive knockout wins, all of her Strikeforce victories have gone to decision.
Modafferi, meanwhile, fights for Strikeforce for the second time. Serving as a late replacement for Erin Toughill at this past November's "Fedor vs. Rogers" co-promotion, the Japanese-based American moved up a weight class and ultimately suffered a first-round submission loss to notable Marloes Coenen.
Since that loss, Modafferi scored a submission win over Molly Helsel at a King of the Cage event, and on May 21, she edged female standout Tara LaRosa (18-1 at the time) via split decision in a heavily praised "Moosin: God of Martial Arts" pay-per-view bout. Modafferi has now won eight of her past nine fights.
Ron "Abongo" Humphrey (7-1 MMA, 1-1 SF) vs. Mike Kyle (16-7-1 MMA, 1-2-1 SF), Cory Devela (9-4 MMA, 1-2 SF) vs. Bobby Voelker (21-8 MMA, 1-1 SF) and Thomas Diagne (1-1 MMA, 1-1 SF) vs. Caros Fodor (5-2 MMA, 0-0 SF) round out the main card.
