Maravilla
Striker
He's not even an ex-champ, but yeah I know what you mean. Fought Joshua as well as Parker and Povetkin, so is at least a familiar name and he will give it a go, but limited risk and a safe fight which will generally be fairly well accepted as a first fight at the new weight.
Just had to look him up, never heard of him.
Fury-Schwarz and Warrington-Galahad as a double header PPV. Exciting times
