Poke hopes to return
Torquay goalkeeper Michael Poke is facing a battle to be fit for their vital rearranged clash with Barnet.
Poke would have missed the visit of the Bees to Plainmoor on Saturday with a rib muscle injury but the match was postponed before kick off after heavy rain.
That extra recovery time means there is a chance the former Southampton man could come back into the starting line-up.
Former Exeter keeper Martin Rice, who had been deputising for Poke, picked up a slight knock in the 1-0 loss at Gillingham while winger Danny Stevens (groin) and midfielder Craig Easton (calf) are close to returning to first-team action.
Knill will be without winger Jordan Chapell after he returned to parent club Sheffield United on Thursday following the departure of Blades boss Danny Wilson.
Barry Fuller will return from suspension for Barnet.
The defender has completed a two-match ban and would have returned on Saturday.
Fuller is poised to replace Ross Jenkins in Edgar Davids' squad after the midfielder went back to Watford at the end of his loan spell.
Player-boss Davids is still without Crystal Palace loanee Kyle De Silva, who completes a three-match ban for his red card against the Daggers, while fellow strikers Steve Kabba (knee) and Ricky Holmes (foot) remain on the sidelines.
Jamal Lowe played for the reserves in midweek to build up his fitness and could be involved as Davids is considering playing two up front for the crucial survival battle.
