Zakuani has scored one goal in three games for Peterborough

Peterborough United defender Gabriel Zakuani is a doubt for Saturday's clash against Leeds with a bruised foot.

Zakuani, 22, who is loan from Fulham, limped off early on in Posh's 2-1 win over Milton Keynes Dons at the weekend.

Ferguson told BBC Radio Cambridgeshire: "He's got a really badly bruised instep, and I've had it myself - it's going to be there for a while.

"It's just one of those things, but that's why we have a squad. Chris Westwood was excellent on Saturday".
