BOLTON boss Sam Allardyce was today sweating on the fitness of Colin Hendry before finalising his side for tonight's FA Cup fifth round replay at Ewood.

The former Rovers favourite is currently nursing a calf strain in the wake of Wanderers' battling 1-1 draw at Fulham on Sunday.

But Allardyce is hopeful the big Scot will pull through in time to take his place in the centre of defence as Bolton seek revenge for their 4-1 defeat in the League at the Reebok 13 days ago.

Bo Hansen (calf) and Simon Charlton (thigh) are also rated as doubtful tonight while Jamaican winger Ricardo Gardner is a definite non-starter after suffering from concussion.

But, those injury worries apart, Allardyce is expected to name a full strength side as he looks to settle a score with a place in the last eight at stake.

"Blackburn are probably the in-form team in the league because they've won most of their last five or six games," said Allardyce.

"Going into the original cup tie, Graeme said he was going into a difficult period of four games on the trot away from home and they haven't lost any of them.

"So we have to try and disrupt that sequence.

"Tonight we want to prove to everybody that that was just a bad 45 minutes we had here against Blackburn in the League."

Bolton will choose from: Banks, Bergsson, O'Kane, Warhurst, Hendry, Charlton, Elliott, Nolan, Frandsen, Farrelly, Passi, Hansen, Ricketts, Holdsworth, Barness, Wheatcroft.
