Worcestershire CCC trio Ben Twohig, Zen Malik and Josh Dell are part of the revised England Under-19s squad for the Royal London One-Day Series against Sri Lanka which starts at Wormsley next Wednesday.
But a fourth Worcestershire player, paceman Josh Tongue, has been forced to withdraw through injury.
Twohig, Malik and Dell are also part of the squad for the current 'Test' series against Sri Lanka with Dell playing in both matches at Fenners and Northampton.
Spinner Twohig will rejoin the Under-19s after being released for the Specsavers County Championship clash with Kent at Canterbury where he has acted as 12th man.
New Road Academy batsman Ollie Westbury, who scored 196 in the first 'Test' against Sri Lanka at Fenners, is not part of the 50 over squad.
Warwickshire’s George Panayi and Yorkshire’s Harry Brook have been called into squad.
They replace Tongue and Tom Moores, the Nottinghamshire wicketkeeper-batsman who is currently gaining senior experience in all formats of the game in a loan spell at Lancashire.
Middlesex's Max Holden – Westbury's opening partner in the two 'Tests' – will skipper the side.
