Peterborough United manager Darren Ferguson says defenders Craig Morgan and Gabby Zakuani may struggle to win back their places in his side.

Morgan missed Saturday's 2-1 win at Walsall on international duty with Wales, while Zakuani was away with the Democratic Republic of Congo.

Midfielder Charlie Lee and transfer-listed defender Keiran Charnock filled the void in central defence for Posh.

"They were outstanding. It's given me a problem for next week," Ferguson said.

The match also saw Aaron Mclean, Dean Keates and Shane Blackett return from injury with all three players fit enough to make the bench.
