New signing Kane Ferdinand could make his full Peterborough debut when Posh resume Championship action.
Ferdinand, a £200,000 addition from Southend during the last transfer window, will be included in the squad that travels to Turf Moor and could be a surprise starter. Manager Darren Ferguson was impressed with Ferdinand's performance in a reserve-team match against Luton this week, even though he described the 3-0 defeat as 'disgusting and embarrassing.'
"Kane is going to be a big player for us. He can play in several midfield positions, which suits the way we play," said Ferguson. "He can play in the centre of midfield or on the right of a diamond. He will certainly be with the first-team in Burnley and he could even start."
Winger Nathaniel Mendez-Laing, who has not played a minute of competitive football this campaign after suffering a hamstring injury during a pre-season friendly at Stevenage, could be another starter in Lancashire on Saturday after also impressing Ferguson against Luton.
