But Williams can add three new signings to his squad. French striker Jonathan Tehoue has arrived on a free transfer and Leicester midfielder Nicky Adams and rookie Fulham defender Matthew Briggs have joined on loan.
Orient's last three games have been postponed but the enforced break means full-backs Stephen Purches (illness) and Charlie Daniels (knee) are back to fitness along with strikers Ryan Jarvis (illness) and James Scowcroft (groin).
Midfielder Sean Thornton also returns after serving a one-game ban against Southend.
