Walsall duo Dwayne Mattis and Darren Byfield are very doubtful for the visit of Hartlepool.
Midfielder Mattis (Achilles) and much-travelled striker Byfield (knee) were both expected to be okay for last weekend`s 1-1 draw at Swindon but failed to pass fitness tests.
And their involvement this weekend is again under serious threat as the Saddlers look to continue their recent turnaround in form which has seen them lose just one of their last five games.
Club captain Mark Hughes serves the final game of his two-match ban, meaning Clayton McDonald and Manny Smith should again form a partnership at the heart of defence.
Midfielder Mark Bradley also sustained a knock to his knee while playing for the reserves in midweek but is hopeful of being available.
Hartlepool director of sport Chris Turner must decide whether to keep faith with his winning side or make changes.
The Pools beat promotion hopefuls Colchester 3-1 last weekend to secure back-to-back wins and keep themselves seven points clear of the relegation zone.
Defender Sam Collins shook of the hip injury he sustained in the 3-0 win over Stockport to play the full 90 minutes against the Us and will be looking to retain his place in the starting XI.
Denis Behan continued his rehabilitation from an ankle injury by playing almost 40 minutes in the reserves on Wednesday but, if he does make the squad, it is likely to be as a substitute as Turner does not want to rush the striker back.
