Danny Wilson says a few of his players are nursing 'bumps and bruises' in the aftermath of Tuesday's win at Hartlepool United.
Goals from Dave Kitson, his second in successive games, and a late winner from Paul Gallagher, his first in United colours, secured the points at Victoria Park in what Wilson described as a 'confrontational' game, not helped by the blustery and wet conditions.
Looking ahead to Saturday's trip to the capital to face Leyton Orient, the Gaffer said: "We have got a few bumps and bruises from Tuesday night but everyone should be fine.
"We are travelling down on Friday and will have a light session, so we will see how that goes before making any decisions."
Lecsinel Jean-Francois is continuing his rehabilitation programme at United's Shirecliffe base, but isn't expected to return to action until later this month.
Meanwhile, O's boss Russell Slade, whose team won 2-1 at Walsall in midweek, saw Lloyd James return from an ankle injury on Wednesday in a behind closed doors friendly against West Ham United.
James played an hour, with strikers David Mooney and Michael Symes also featuring in a bid to force themselves into contention for the weekend.
Mooney scored twice in the 3-2 win over the Hammers.
