An undisclosed injury has forced Chad Griggs (11-2 MMA, 0-1 UFC) to withdraw from UFC on FOX 4.
In his place goes Wagner Prado (7-0 MMA, 0-0 UFC), who now fights light heavyweight Phil Davis (9-1 MMA, 5-1 UFC) at the Aug. 4 event, which takes place at Staples Center in Los Angeles. The event's main card airs live on FOX while prelims go to FUEL TV and Facebook. The promotion has yet to confirm broadcast assignments for the fight card.
MMAWeekly.com first reported the shift, and MMAjunkie.com (www.mmajunkie.com) confirmed it with a source close to the event. Link
