Worcestershire have been given permission by the England and Wales Cricket Board to play century-maker Moeen Ali in Sunday's home LV = County Championship clash with Glamorgan at New Road.
Ali earned glowing praise for his unbeaten 108 in the second Investec Test with Sri Lanka at Headingley after batting through the entire final day to almost salvage a draw.
The majority of the squad will meet up at Loughborough on Tuesday and Wednesday for a training camp ahead of the five match series with India.
But Ali, who is not centrally contracted to the ECB, will be allowed to turn out for his county against their Welsh opponents.
The 27-year-old will have the chance to hone his batting and spin bowling skills in the four-day fixture before the first Test gets underway at Trent Bridge on July 9.
Worcestershire Director of Cricket Steve Rhodes has thanked the ECB for their understanding and allowing Ali to play.
He said: "I'm delighted that the ECB understand that the best preparation for Moeen for a Test match is to play in this four-day game against Glamorgan."
Ali received praise from England head coach Peter Moores and captain Alastair Cook for the quality of his innings under immense pressure at Headingley.
He also demonstrated his bowling potential with two wickets in two overs during Sri lanka's second innings including Kumar Sangakkara for the second time in the series.
Ali will be making his fifth Championship appearance of the season and scored a brilliant 162 in his last four-day county game against Surrey at the Kia Oval.
