The midfielder, who penned a permanent deal with North End at the start of January, was sent off against Bradford in midweek and was due to serve a three-game ban before the FA overturned the decision on Thursday.
Striker Kevin Davies, meanwhile, will complete a three-match suspension of his own but will return for the FA Cup replay with Nottingham Forest next Wednesday.
Otherwise, Lilywhites boss Simon Grayson has a full squad to choose from with the likes of Keith Keane, Chris Humphrey and Lee Holmes ready to replace Kilkenny.
