Greer, the Chicago product who taunts potential KO victims with custom-made pillows, is knocking on the doorstep of a world title shot. He has won 19 fights in a row and is currently the WBO No. 1 contender at bantamweight. Plania, meanwhile, has won eight straight bouts since a March 2018 decision loss to Juan Carlos Payano, a fight that propelled Payano to a world title shot against pound-for-pound great Naoya Inoue.
