It’s never good news when a bout loses one of its participants due to injury but every so often the unfortunate circumstances result in a more intriguing match-up. Such a scenario has unfolded in the case of UFC welterweight Robbie Lawler’s summer scrap, as original UFC on FOX 8 adversary Tarec Saffiedine has been replaced by Siyar Bahadurzada after the former Strikeforce champion withdrew for undisclosed health issues.

UFC officials have confirmed the change to the July 27 show.

Like Lawler, the 21-5 Bahadurzada is a cement-fisted slugger known for knocking foes into next week. Seventeen of his victories have featured a finish including eleven TKOs with the most notable example coming against Paulo Thiago in Bahadurzada’s Octagon debut.

The 20-9 Lawler certainly shouldn’t be afraid to engage Bahadurzada come showtime based on his own reputation for rocking opponents. “Ruthless” Robbie can lay claim to seventeen strike-based stoppages such as those against Matt Lindland, Melvin Manhoef, and most recently Josh Koscheck.
