The Wanderers opened their pre-season programme on Wednesday night with a fine 7-1 victory over Ballymena United at The Showground and will be hoping for more of the same when they take on Ronnie McFall's side tommorow lunchtime.
The Trotters look set to welcome back mid-week absentees Youri Djorkaeff, Jay-Jay Okocha, Ricardo Gardner and Simon Charlton whilst Greek international midfielder Stylianos Giannakopoulos stands by to make his Bolton debut.
Trialist Kevin Davies is also expected to get another run out for Sam Allardyce's men after the Bolton boss confirmed he would like to take another look at the former Southampton striker in action before deciding on whether to make him a permanent addition to the side.
Portadown include Vinny Arkins who played under Allardyce at Notts County and former Blackburn Rovers youngster Gary Hamilton in their line up as well as the former Wigan Athletic defender Neil Ogden
