Ferguson has decision to make ahead of the weekend

Peterborough United manager Darren Ferguson is facing a shortage of centre-backs ahead of the trip to Walsall on Saturday.

Craig Morgan and loanee Gabby Zakuani are both away on international duty and Chris Westwood is struggling to be fit.

Ferguson told BBC Radio Cambridgeshire: "Westwood went for a jog on Sunday and felt his calf.

"[Midfielder] Charlie Lee will play there on Saturday, but we're hoping Westwood will be fit as well."

Should Westwood fail to make the match Ferguson may be forced to recall out-of-favour Keiran Charnock.

Shane Blackett is still some way short of a return to match action after dislocating his shoulder in training last month.
