Kevin Pietersen will make his first appearance since being dropped by England when Surrey face his old club Hampshire in the CB40 on Sunday.
The batsman was left out of the team for the Lord's Test against South Africa following unrest in the England dressing room.
He later admitted sending "provocative" texts to some of his friends in the South Africa squad.
"He is available. He will be in the squad," a Surrey spokesman said.
Pietersen scored 234 not out in his last appearance for Surrey in a drawn County Championship match against Lancashire on 11 July.
