He pulled out with gum disease when he was due to fight Gary St Clair,with Guzman...I aint saying Guzman ducked him,all I know is that he broke a contract to fight Scott Harrison for his WBO featherweight belt and chose instead to step up to super-featherweight.
With Marquez well like I said before Harrison was even in trouble in Spain Marquez pulled out to fight Jaca so the argument about Marquez not wanting to wait around does'nt hold up as at that time Harrison was'nt in trouble in Spain as yet so who knows why he did pull out?,maybe he is physic,lol.

All I'm saying is Harrison is scared of nobody!,he's a warrior
