Wilder is going to take the polish bum as a tune up fight after injury. I think thats bs. He's a champ! champion should fight the best one out there. if you are contender then tune ups are fine, but c'moon champion doesn't need tune ups. If champ can't defende his title against the best one then he should give his belt away.
I'm fine with tune ups if they take them in addition to three hard fights each year. Take all the tune ups you want, but you're still gonna' fight your #1 challenger in 4 months. If you want to fight every day, I'm not gonna' stop you.
