Vitali should toy with him after about the 3rd round. Even if Shannon is in great shape he's going to tucker out pretty quick vs Vitali because Vitali will make him move around the ring both to attack Vitali and also to get away from Vitali's power. Shannon's legs will tire out and after that it should just be a walk in the park.

Vitali has a Ph.D. in administering KO's and Shannon is going to find that in the boxing ring that certification very valid and it's going to take more than an inhaler to wake his goofy ass up once Vitali blasts him.
