Sheffield United have injury concerns over three players ahead of the Championship play-off final against Burnley on Monday.

Striker Darius Henderson and on-loan midfielder John-Joe O'Toole are both struggling with Achilles problems and face a race against time to recover to face Owen Coyle's side.

Former Chesterfield striker Jamie Ward is also rated as doubtful with a hamstring injury.

All three missed the Blades' victory over Preston in the second leg of the semi-final at Bramall Lane and Blades boss Kevin Blackwell will give them until the last minute to prove their fitness.

Blackwell is likely to persist with playing on-loan full-back Greg Halford as an emergency striker following his match-winning goal against Preston last time out.
