Scunthorpe United have brought in Tranmere defender Mark McChrystal on a one-month loan deal.
The 28-year-old completed the move in time to start Tuesday's home clash against fellow strugglers Bury.
McChrystal, who is a former Northern Ireland Under-21 international, has made 41 appearances for Rovers since joining from Derry City.
McChrystal's arrival provides cover for the injured David Mirfin and suspended Paul Reid.
Reid is banned for three matches after failing to overturn his red card against Notts County on Saturday.
