Former Strikeforce champion Tarec Saffiedine (14-3 MMA, 0-0 UFC) is the latest victim of the injury bug, and fellow welterweight Siyar Bahadurzada (21-5-1 MMA, 1-1 UFC) has stepped as an injury replacement and now fights Robbie Lawler (10-9 MMA, 5-3 UFC) at UFC on FOX 8. UFC officials today announced the switch. UFC on FOX 8 takes place July 27 at KeyArena in Seattle. The main card airs on FOX following prelims on FX and Facebook. Bahadurzada vs. Lawler is expected to maintain its main-card slot. Bahadurzada looks to rebound from a UFC on FUEL TV 8 decision loss to Dong Hyun Kim earlier this year
