Leyton Orient will be without midfielder Romain Vincelot for this evening's home game against Oldham.
Vincelot picked up his tenth booking in Saturday's draw at Walsall and will miss the next two matches through suspension.
His place is likely to go to either Scottish midfielder Jamie Ness or Marvin Bartley. Shaun Batt is a doubt after he missed the weekend game with a virus while Moses Odubajo has picked up an ankle injury.
Russell Slade's side need to take maximum points after they slipped four points behind second-placed Brentford on Saturday.
Reflecting on their chances of automatic promotion, Slade said: "It's not out of the question no. I bagged it as three big games, this one and our two home matches against Oldham and Bradford. I think that's got to be our focus and then we can see where we are from there.
"We certainly need two big efforts on Tuesday and Saturday at home to see if we can take maximum points."
Oldham are still not safe from relegation and will be hoping to build on their 1-1 draw at home to Orient back in October.
