Here is the reason why Molitor did not take the fight, the snippet below was after his fight last month:

Molitor had just dismantled Mexico's Fernando Beltran Jr. by unanimous decision and couldn't hide his excitement at the well-earned month away from workouts that lie ahead. "No running, no training, no nothing," he said.
There will also be a vacation - "somewhere far, far away, with maybe a few drinks" - before he returns to the gym in Mississauga, Ont., where he trains with Chris Johnson.

""I've got to take some time off to get that hunger back a little bit."
