Tony Thompson seems available. Is he injured? if not, then Thompson-Wilder makes sense. Thompson is old but he is still decent opponet. This fight needs to happen, Thompson deserves one more title shot. What is Wilder waiting for?
Thompson can come into the fight juiced to the gills and he'd still be too old slow and weak to compete with Wilder.
high risk low reward. Seeing as how they were scouting Arrerola I doubt they'd be down for a serious threat like Thompson
