Best Mate's assistant trainer Terry Biddlecombe reports the triple Gold Cup winner to be "in excellent form" as he recovers from treatment for a cough.
The gelding was beset by a number of problems in last week's Lexus Chase, when he was beaten seven lengths by Beef Or Salmon, including a mistake at the first fence, unsuitably soft ground and a cut on his head on the way over to Ireland.
His handler Henrietta Knight subsequently revealed that Best Mate had started coughing a day after the race, and he was put on a week's course of antibiotics.
"I fed him this morning and he tried to knock me over," said Biddlecombe.
"He has only coughed for a couple of days - a dry cough, no runny nose. He is in excellent form and will be ridden out tomorrow.
"It was one of those unfortunate things. He had two or three things go wrong with him. Also, Beef Or Salmon is a very, very good horse, but come Cheltenham and good ground, it will be a different story."
Rodi Greene hopes to return from nearly five months on the sidelines at Taunton on Monday. He has been out of action since August 10th having dislocated his shoulder riding Lost In Normandy at Newton Abbot.
