PAUL TERRY is a doubt for Saturday's game with Millwall with a back injury.

The O's midfielder missed training in the latter half of the week with the back complaint and may not recover in time for Saturday's derby duel.

He will join Brian Saah on the sidelines after he picked up a hamstring injury in last weekend's victory over Crewe - a strain that's likely to keep him out for two to three weeks.

Wayne Gray remains on the long term injured list as he continues his recovery from a ruptured cruciate liagament.
