He just fought 4 months ago, so it's not like he has been out of the sport a long time and he has the same time to prepare as the Black Beast who has the cardio/stamina that is on par with Kimbo Slice/Houston Alexander. Haha!
As you said, he also doesn't need a lot of time to gameplan. He is going to incorporate a lifetime of wrestling to wrestlefuck Lewis like he did andy.
This is easy money. He doesn't even need to lay-off the Popeye's chicken! Then he gets to enjoy Thanksgiving and Christmas with the family before he prepares for his final fight.
