Wycombe Wanderers goalkeeper Martin Taylor has joined the Tykes on loan until the end of this season.
However, a 24-hour recall clause has been built into the agreement.
The experienced Taylor has had spells at Derby, Scunthorpe and Crewe before joining Wycombe in 1997.
The 36 year old is expected to start on the bench tomorrow after a man of the match performance from Matt Ghent against Tranmere on Tuesday.
