Yeovil Town goalkeeping coach Gareth Stewart has been drafted in to face Hereford in the FA Cup on Saturday.
West Ham loanee Marek Stech has been their first-choice keeper since October but is currently on international duty with the Czech Republic Under-21 squad.
Stewart, 31, was on the bench for the Glovers against Carlisle last month because an injury to former Norwich loanee Jed Steer, but did not feature.
"We've got confidence in Gareth," boss Terry Skiverton told BBC Somerset.
Former Bournemouth keeper Stewart was appointed coach at the start of the year and has not played in the Football League since March 2008.
"He has played more games than all of the loans I have had as manager," continued Skiverton.
"We do not need to sing from the rooftops that our player has been away on international duty, we have just got on with it and we have got more than enough confidence in Gaz.
"He is not a young kid. He is more than good enough to play for our first team."
Meanwhile, Skiverton is hoping loan players Darren Purse, Max Ehmer, Connor Clifford, Oli Johnson, Gavin Massey and Jon Obika will all be given permission by their parent clubs to take part in Saturday's Cup tie.
"We are still waiting on news about all of the loan signings for the future and we are still waiting. We have had no 'nos' come back yet about players playing on Saturday," he added.
"This is a must-win game for us. I definitely want a cup run and we will be making sure we do everything to get through this round."
