The move is not unexpected, as McCarthy, son of former dual star Teddy, impressed in a brief cameo in the drawn game, making an impact with his ball-winning skills in the half-forward line, a problem area for much of the game for the Rebels.
McCarthy was withdrawn minutes after his introduction with a minor leg injury but he has since recovered and manager Jimmy Barry-Murphy has handed him the number 11 jersey for Saturday night.
There is no starting place for Stephen Moylan, however, though the Douglas man also impressed when coming in as a substitute in the drawn game.
The rest of the Cork team lines out as per the first match, but there will be keen interest in whether, for instance, Brian Murphy abandons his wing-back post to track Tony Kelly as he did in the drawn game, with Christopher Joyce, named at centre-back, moving to the wing as he did in that match.
Contrary to speculation, neither Aidan Walsh nor Ciaran Sheehan of the Cork football squad have been included in the hurling panel.
Meanwhile, former Clare boss Mike McNamara expects Cork to change tactics for the game.
He believes Jimmy Barry-Murphy and his sideline team will employ a negative approach after the Rebels struggled to live with the pace and intensity of Clare’s hurling three weeks ago and consequently, McNamara claimed the Cork manager will have instructed his troops to prevent an open, flowing game this time.
Each of Clare’s starting six forwards, as well as midfielder Colm Galvin, found the target from open play in the drawn game and the Scariff native asserted Davy Fitzgerald’s outfit is simply too strong in the key areas to be dragged into a scrap.
“I think the next day will be much more dour, less free-flowing game,” said McNamara.
