Aston Villa goalkeeper Matija Sarkic has been recalled from his loan spell at Livingston.
After being an unused substitute in their first seven Scottish Premiership matches, the 22-year-old established himself as the team's first choice goalkeeper.
The Montenegrin started their last 14 league matches, keeping six clean sheets along the way.
Sarkic also appeared four times in the Scottish League Cup, helping Livingston to reach the quarter-finals.
The stopper will add depth at the goalkeeping position after Tom Heaton sustained an injury at Burnley on New Year's Day, joining Jed Steer on the sidelines.
