Bury boss Alan Knill could be without defender Tom Lees for the home clash with leaders Chesterfield.

The centre-back clashed heads with Stockport loanee Matt Paterson in the early stages of Saturday`s 2-1 defeat at Edgeley Park and was replaced by Ben Futcher after just 17 minutes.

Lees will be assessed ahead of the Spireites` visit but on-loan Manchester United striker Nicky Ajose faces up to six weeks out with a knee injury.

Knill, meanwhile, is refusing to panic after his side crashed to defeat against lowly County at the weekend.

He said: "On another day we would have scored five and we just have to realise that this happens sometimes and not get too carried away with defeats because I think we are playing pretty well."

Chesterfield will assess Dwayne Mattis ahead of the trip.

The midfielder did not reappear for the second half of the defeat to Burton on Friday night due to a sore calf.

Jack Lester missed out at the Pirelli Stadium because of a virus and the veteran striker will also be monitored.

The league leaders are without a win in four matches but boss John Sheridan remains upbeat.

He said: "We will stay positive because we are still top of the league and in a healthy position.

"But we do have to look at ourselves because for the last three or four games our performances haven`t really been there and things aren`t going our way at the moment."
