The 36-year-old who made 13 appearances for the Whites while on loan from Fulham at the start of the 2006/7 season, will play for the reserves against Scunthorpe on Tuesday.
He has been without a club since his release from Charlton in the summer. Jason Brown, on loan from Blackburn, is the only fit senior goalkeeper at the club with Kasper Schmeichel (foot) and Shane Higgs (hamstring) injured.
Alan Martin is on a season-long loan at Barrow while Alex Cairns is also on the injured list.
