Bristol Rovers keeper Kevin Miller has joined Derby on loan.
Miller, 36, was left out of Saturday's team to face Mansfield and was told by boss Ian Atkins that he was unlikely to play for the rest of the season.
The experienced keeper will provide cover for Derby after an injury to their number two keeper Lee Grant.
Meanwhile, Rovers have brought in defender Jon Bass on a short-term contract after the 28-year-old impressed during a trial period.
