On-loan Tottenham Hotspur keeper David Button has been ruled out of this afternoon’s League One basement clash between Leyton Orient and Chesterfield at the B2net Stadium.

The stopper sustained a shoulder injury in the dramatic mid-week Carling Cup victory over Bristol Rovers and his place between the posts is taken by Lee Butcher.

Elliot Omozusi also comes into the defence after Scott Cuthbert was ruled out with a calf problem, while the third change from mid-week sees Marc Laird replace Leon McSweeney, who is on the bench.

The pointless O’s will be hoping to build on that cup success against a Spireites side who are also still seeking their first league victory and sit one place above today’s opponents in the table after picking up just a single point so far.

The hosts lost 2-1 at Exeter City in their last outing and manager John Sheridan makes two changes, giving a debut to French-born winger Alex Mendy, while Jack Lester returns up front. Dean Holden and Scott Boden make way, both dropping to the bench.

Chesterfield: Lee; Talbot, Ford, Grounds, N Smith; Mendy, Allott, Johnson, Whitaker; Lester, Westcarr. Substitutes: Holden, Fleming, Morgan, Boden, Bowery.

Leyton Orient: Butcher; Omozusi, Chorley, Forbes, Daniels; Laird, J Smith, Dawson, Cox; Mooney, Cureton. Substitutes: McSweeney, Porter, Tehoue, Odubajo, Richardson.
