Bristol City have opted against offering a full-time contract to trialist Martin Lejsal.
The former Czech Republic U21 international had spent the last eight days training with the Robins in the hope of landing a deal.
City boss Gary Johnson held initial discussions regarding the prospect of signing the keeper, but has decided against striking a deal.
With Lejsal's parent club, FC Brno, calling for a decision to be made before this weekend's pre-season friendly against Wycombe, Johnson admits he was unable to justify bringing in the shot-stopper.
"His club were pushing for a decision early as there had been interest from (Dutch club) Heerenveen," the Robins coach told the club's official website.
"We put Martin through a stringent medical but decided at this time we couldn't offer him anything, it wouldn't be right for the club."
While deciding to pass on Lejsal, Johnson admits he is still in the market for a new keeper as Adriano Basso is transfer listed and Stephen Henderson is sidelined with a fractured toe.
"We'll carry on searching and we have a few irons in the fire," he said.
