Condit (27-5) was scheduled to fight welterweight champion Georges St-Pierre last month at UFC 137 after replacing Nick Diaz, but St-Pierre was sidelined by a knee injury and Diaz earned the next shot at GSP with a win over BJ Penn in the new UFC 137 main event.
Koscheck (16-5) stepped in to score a first-round knockout of Matt Hughes in September to bounce back from a December loss to St-Pierre the followed a three-fight win streak.
St-Pierre and Diaz meet in the UFC 143 main event and the winner of Condit vs. Koscheck will be a front-runner for the next title shot.
