Graeme Swann has been ruled out of England's fifth One-Day International against Sri Lanka with a hamstring strain.
The Nottinghamshire off-spinner became the first England spinner to pick up four wickets in a ODI since 2002 in Monday's victory at Dambulla and has averaged 28 runs with the bat in October's series success.
But having played his way firmly back into the reckoning a scan to his left thigh has thrown his blossoming international future into doubt.
A hamstring tear has been discovered and Monty Panesar now looks set to replace his former Northamptonshire team-mate for the final ODI on Saturday morning.
Coach Peter Moores told Sky Sports News: "It's a grade two tear of his hamstring, which he got in the last game. It was painful all the way through, so he won't play because he could make it worse.
"At the moment it looks like it will be two weeks before he'll be fit to play again.
"He's obviously very much in the frame for the Test matches in December and if he gets selected then he'll be available for those, which is important."
Paul Collingwood's side already holds an unassailable 3-1 lead in the five-match series, but will want to close on a high with the Test series against Sri Lanka starting on 1st December.
