Darryll Holland will miss his three rides at Lingfield, due to a stomach bug.
However, he is confident he will be back in action on Wednesday at Yarmouth, before jetting off for Ayr's two fixture on Thursday and Friday.
Holland's agent, Matt Chapman, said: "Darryll went up to Thirsk on Monday evening and must have eaten something dodgy as he didn't have the best of nights.
"He thought it was best to take today off as he might not be able to give his rides 110 per cent.
"We are sure he will be back in action at Yarmouth - no problem."
Holland has ridden 10 winners in the last two weeks and has notched up 25 victories this season.
