Less than two weeks out from the fourth, World Series of Fighting even on August 10th, the promotion has announced that bantamweight Joe Murphy has been forced to withdraw due to a rib injury. As a result, UFC veteran Jared Papazian will step in to fight John Robles at the event, which will be hosted by the Citizens Business Bank Arena in Ontario, Calif.

Papazian (15-10) is coming off a submission loss to Brandon Bender while competing for the National Fight Alliance, after scoring a UD win over Terrion Ware at a BAMMA USA card in March. The 25 year-old fighter went 0-3 during his time with the UFC.

Robles (7-1) has scored back-to-back wins over Juan Rivas and Steven Barajas while fighting for MEZ Sports.

WSOF 4 will feature a light-heavyweight bout between Tyrone Spong and Angel DeAnda in the main event and will be broadcast on the NBC Sports Network.
