Henderson said: "Simsonsig is very good. He is in good form and does not take a huge amount of work. He has been very good in his two runs over fences and I think he knows what he has to do.
"He has tremendous ability and enthusiasm for racing. It will do him no harm for Overturn to give him a lead – he has wonderful pace."
