Josh Koscheck has been injured and forced out of his UFC 163 welterweight fight against Demian Maia next month.
Koscheck (17-7 MMA, 15-7 UFC) and Maia (18-4 MMA, 9-4 UFC) were scheduled to meet as part of the main card of the event, which takes place at HSBC Arena in Rio de Janeiro on Aug. 3. The main card airs on pay-per-view following prelims on FX and Facebook. UFC officials have not yet revealed which preliminary card fight will take the place of Koscheck-Maia on the pay-per-view broadcast, though it is likely a featured prelim between Brazilian Vinny Magalhaes and Anthony Perosh will be elevated to the main card.
Maia was looking for his fourth consecutive win and potentially the next shot at the welterweight title. Since dropping from 185 to 170 pounds, the submission specialist has won bouts against Dong Hyun Kim, Rick Story and Jon Fitch.
The final UFC 163 card now includes:
Jose Aldo vs. Chan Sung Jung - for featherweight title
Phil Davis vs. Lyoto Machida
Cezar Ferreira vs. Clint Hester
John Lineker vs. Phil Harris
Vinny Magalhaes vs. Anthony Perosh

Neil Magny vs. Sergio Moraes
