The 43-year-old will be determined to change the fortunes of the club – who currently sit bottom of the League One table with just nine points from 13 games.
During his playing career on the Fylde Coast, the retired defender was involved in two promotions, and will be hoping to enjoy similar levels of success from the dugout in the long-term.
For now, his focus will be on guiding the Seasiders to their first league win in over a month, which will entail dealing with a pretty hefty injury situation.
In last Saturday’s 1-1 draw with Wycombe Wanderers, Albie Morgan was withdrawn at half time due to a calf problem, while Michael Ihiekwe was forced off after an awkward landing in the final moments of regular time.
The former of the two underwent a scan this week, while the latter is currently following concussion protocols.
George Honeyman is making progress, but the Peterborough game is set to come too soon for him, while James Husband is a few weeks behind him.
Hayden Coulson will continue to be assessed after fracturing his arm in Blackpool’s last away outing against Stockport County, and should return to contact training next week.
Dale Taylor was forced off in the same fixture with a hamstring injury, and forms part of a longer term list of absentees which also includes Danny Imray and Niall Ennis.
Here’s our predicted XI and bench to take on Peterborough:
