McCready a doubt and Ricketts remains suspended
Crewe centre-back Chris McCready is a doubt for the visit of Walsall in League One.
The defender suffered a hamstring injury in the defeat at Carlisle, where he was replaced late in the game by George Abbey.
And Abbey and Daniel O'Donnell are on stand-by should McCready not recover in time.
Right-back Danny Woodards is expected to be fit after he also tweaked his hamstring at Brunton Park, while Calvin Zola could return from an ankle problem.
New signing Clayton Donaldson could be in line for his debut after completing his move from Scottish Premier League club Hibernian.
Eugen Bopp is not expected to be fit as he continues to recover from the abductor strain he suffered against Brighton on the opening day of the season.
