Worcestershire Seconds will be without Joe Clarke and Ed Barnard for today's (Tuesday's) Second Eleven Trophy clash with Durham at Brandon.
Wicket-keeper Clarke and batsman Barnard are on England Under-19 duty with two Tests and five ODI's scheduled against South Africa during August.
Alex Milton will take over the wicket-keeping duties from Clarke who last week scored the county's highest ever Second Eleven Championship score of 222 against MCC Young Cricketers at Kidderminster.
Batsman Jamie Harris is brought into the 12 man squad.
The Academy player has made one previous appearance for the Seconds this season, scoring 22 not out in the rain-affected Second Eleven Championship match with Nottinghamshire at Worcester Royal Grammar School.
Harris also plays for Himley in the Birmingham League.
The game has been put back 24 hours to allow the Worcestershire players to attend yesterday's Thanksgiving Service for Damian D'Oliveira at New Road.
Worcestershire Seconds (from): Pardoe, Harris, Andrew, Rhodes, Hepburn, MacVicar, Milton, Williams, Russell, Cessford, Harrison, Whiles.
*George Rhodes warmed up for today's clash by scoring a century for Barnards Green in the away Birmingham and District League clash with Moseley.
Rhodes reached his 50 off 84 balls and went to his century off 136 deliveries with 12 fours.
But his efforts proved in vain as Moseley overhauled Barnard Green's 221-9 in 50 overs and won by six wickets.
County opener Matt Pardoe also scored 76 for Kidderminster in their league clash with Knowle and Dorridge.
It helped Kidderminster to claim a winning draw as they amassed 332-7 and restricted Knowle and Dorridge to 217-7.
