While it makes little sense in terms of the direction both fighters are going, the welterweights appear on a collision course for August 3 and Brazil. No location has been announced for the event.
Koscheck (17-7) is a former No. 1 contender in the 170-pound division, but has lost two straight, including a devastating defeat at the hands of Robbie Lawler earlier this year.
Maia, though, has won three straight to improve to 18-4 since moving down from middleweight. He is also a former title contender, having been defeated by Anderson Silva.
