Dael Fry and Grant Hall are both sidelined for the visit of Peterborough while Lee Peltier, who was deputising at centre-back, will serve a one-match suspension. Expect midfielder Paddy McNair and left-back Marc Bola to drop into the back three in their place. Injured trio Marcus Browne, Anfernee Dijksteel and Onel Hernandez all remain unavailable. Marc Bola picked up an injury in training with youngster Williams Koloko likely to deputise. Darren Ferguson could make one change to the side that lost against Bristol City with Jorge Grant replacing Conor Coventry in midfield. Striker Jonson Clarke-Harris is suspended after Posh withdrew their appeal against his four-match ban.
