Injury replacement Siyar Bahadurzada (21-5-1 MMA, 1-1 UFC), who took a spot originally intended for Tarec Saffiedine, has now also been forced with withdraw from UFC on FOX 8.

Taking his place is five-time Strikeforce vet Bobby Voelker (24-9 MMA, 0-1 UFC), who now becomes Robbie Lawler‘s third scheduled opponent.

UFC on FOX 8 takes place July 27 at KeyArena in Seattle. The main card airs on FOX following prelims on FX and Facebook. Lawler vs. Voelker is expected to air on the main card.

Voelker, perhaps best known for an entertaining trilogy series with Roger Bowling during the pair’s Strikeforce run, made his UFC debut in March, where he dropped a hard-fought decision to veteran Patrick Cote, ending a three-fight win streak.

Lawler recently returned to the UFC after a long run with EliteXC and Strikeforce. At UFC 157 in February, he halted a 1-3 skid after dropping from middleweight to welterweight and knocking out perennial contender Josh Koscheck.

Bahadurzada had looked to rebound from a UFC on FUEL TV 8 decision loss to Dong Hyun Kim earlier this year. Prior to that, the Netherlands-based Afghan fighter posted seven consecutive victories, which included winning a 2011 Ultimate Glory tournament and knocking out Paulo Thiago (in just 42 seconds) in his UFC debut.
