Ronny Rios takes a dangerous stay busy fight upon his road to featherweight title contention. The unbeaten Californian squares off versus Robinson Castellanos in a scheduled 10-round bout Friday evening at Fantasy Springs Casino in Indio, California.

Both fighters made weight during Thursday's pre-fight weigh-in festitivitie. Rios (23-0, 10KOs) tipped the scales at 128 lb., while former Top 10 featherweight contender Castellanos (19-10, 12KOs) came in at 127 lb. for their Fox Sports 1 headliner.

In the co-feature, another rising young contender from California graces the TV screen as Antonio Orozco faces faded former 130 lb. titlist Steve Forbes in a scheduled eight-round super lightweight bout. Orozco (20-0, 15KOs) weighed 141.8 lb, slightly lighter than Forbes (35-13, 11KOs) who checked in at 142 lb. 

The telecast opens with rising young super bantamweight prospect Diego de la Hoya in a scheduled four-round affair with Luis Ruiz. 

de la Hoya (6-0, 5KOs)—based out of Mexicali and the younger cousin of Hall of Fame fighter Oscar de la Hoya (who as President of Golden Boy Promotions also serves as his promoter)—weighed 123 lb. for what serves as his fourth appearance at the venue. 

Ruiz (5-2-1, 2KOs) was slightly heavier at 123.6 lb., as he prepares for his stateside debut and his first fight outside of Mexico. The 21-year old has won two straight.
