Josh Koscheck will not get the opportunity to halt Demian Maia’s push up the welterweight rankings at UFC 163 afterall, as the promotion has announced that he’s been forced to drop out. The announcement comes one day after a slew of injuries were announced, which has seen fighters like Bobby Green, Matt Mitrione and Siyar Bahadurzada pulled from this month’s UFC on FOX 8 card.

The UFC’s announcement did not disclose the nature of Koscheck’s injury, but did relay that Maia will not compete on the card. Considering the card is less than a month away it might have been tough to find a replacement. Perhaps the UFC will give this fight another go sometime in the near future? Depending, of course, on how long Koscheck’s going to be out.

So, the news is pretty unfortunate, considering the fight featured the #10 ranked welterweight in Koscheck, battling the #5 ranked Maia. There was also an interesting back story to the fight, since Maia is coming off a unanimous decision win over Jon Fitch, who is Koscheck’s buddy and former training partner. The victory was Maia’s third straight since he moved to welterweight, following his decision loss to newly crowned middleweight champ Chris Weidman.

The bout also presented a massive opportunity to Koscheck, who’s coming off a stoppage loss to Robbie Lawler and a split decision defeat to Johny Hendricks. It’s the first time “Kos” has lost two fights in a row since he turned pro.

The good news is (knock on wood) that featherweight champ Jose Aldo is set to fight Chan Sung Jung at UFC 163, and the card will also feature a compelling light-heavyweight tilt between Lyoto Machida and Phil Davis. The August 3rd event will be hosted by the HSBC Arena in Rio de Janeiro, Brazil and the main card will be available via pay–per-view.
