Tonight at 10 pm (or is it 10:30? different channels tell me different things - we'll see, try 10 first!) on Fox Sports, Yoshihiro Kamegai and Jorge Linares are lined up for showcase fights in Sacramento.

Japanese welterweight Kamegai (21-0, 18 KO) will be facing 20-year-old Mexican prospect Jorge Silva (19-2-1, 15 KO), who replaced veteran Cosme Rivera on short notice. The 29-year-old Kamegai is an interesting fighter who just might be ready to emerge as a contender in the near future, and with the lack of depth in the division in Japan, more fights in the States could help with that path.

Linares (31-3, 20 KO) is well-known at this point, a prodigious talent who has fallen short of expectations due to a shaky chin and some leaky defense along the way. He's lost his last two by stoppage to Antonio DeMarco (despite Linares dominating the majority of the fight) and Sergio Thompson, and is hoping to get well tonight with a fight against 37-year-old Hector Velazquez (52-17-3, 35 KO), a veteran who hasn't beaten a good opponent in some time. But Velazquez certainly isn't feather-fisted, and with Linares, you just never know at this point.
