Boss Micky Adams has doubts over five players as his play-off-chasing Port Vale side prepare to entertain leaders Notts County.
Adams` biggest concern comes between the sticks with regular number one Chris Martin receiving treatment all week having taken a kick to his ankle in training on Tuesday.
Back-up Joe Anyon did take part in some training on Thursday but has still not yet fully recovered from the thigh problem that has ruled him out for the past two weeks.
Should Martin and Anyon not make it in time then youngster Daniel Lloyd-Weston, who has already been told he will be released at the end of the season, will be called upon to make his professional debut.
Imposing centre-back Gareth Owen is battling to overcome an ongoing hip problem while striker Craig Davies is struggling having also taken a kick on Tuesday, this time to his knee.
Louis Dodds, who started on the bench for last weekend`s 1-1 draw at Bury, has been struck down with a sickness bug and will be monitored.
Notts County striker Luke Rodgers will be hoping for a recall.
Rodgers has been the subject of interest from MLS side New York Red Bulls, who are managed by former Magpies boss Hans Backe, but he returned to the bench for the home win over Rochdale on Tuesday night.
However, he may find it difficult to force his way back into the starting line-up as County have been unchanged for the last three games - winning all of them. Therefore, boss Steve Cotterill is likely to pick the same XI for a fourth successive match.
Should he wish to make changes though, Jamie Clapham, Karl Hawley, Ade Akinbiyi, Matt Hamshaw and Johnnie Jackson are also available.
County will be crowned champions of League Two if they win at Vale Park and Rochdale lose at Hereford.
