McCarthy makes new signings
Left-back Clapham, 30, has signed a two-year deal at Molineux after being released by Birmingham City at the end of last season.
The ex-Tottenham and Ipswich player is a veteran of over 300 League matches and will add some much-needed experience to McCarthy's backline.
Midfielder Henry, 23, has joined his hometown club on a three-year contract after they agreed to pay Stoke City an initial fee of £100,000.
A further £75,000 payment is dependent on appearances, while Stoke will also be entitled to 15 per cent of any future sell-on fee.
Henry came through the youth-team ranks at the Britannia Stadium and scored once in 120 League outings for the Potters.
