Sheffield United will be without Joe Riley for their home game against Bolton after the defender dislocated his shoulder.

Riley, on loan from Manchester United, sustained the injury in training this week and is awaiting scan results back at his parent club to learn whether his season is over.

Boss Chris Wilder has no other new injury problems but is expected to make changes again after regularly rotating his squad this season.

Striker Leon Clarke (ankle) is still out, while on-loan Wolves defender Ethan Ebanks-Landell, midfielder Samir Carruthers, winger Jay O'Shea and striker Matty Done are all pushing for recalls.

Chris Long remains a doubt for Bolton when they make the trip.

Boss Phil Parkinson said the forward, who missed out against Bradford with a hamstring problem, was "making good progress", though this fixture may come too soon.

The Burnley loanee will be assessed on Friday, as will Andrew Taylor - the defender having returned to full training on Thursday after a hamstring problem of his own.

New signing Reece Wabara and goalkeeper Mark Howard (hand) played for the development squad earlier in the week and are close to being involved in the first team, but Jay Spearing remains suspended.
