Dundee have made their first signing of the January transfer window.
Central midfielder Ross Callachan joins the Dens Park club on loan from St Johnstone until the end of the season.
The 26-year-old has previously played for Hearts and Raith Rovers.
Speaking on the club's Dee TV, he said: "I'm just hoping to get back playing. I've been surplus to requirements at St Johnstone so I'm just hoping to get back playing.
"I was to get my career on the road again and get back into a starting eleven and kick on from then.
"I'm looking forward to being involved again. Being back in a changing room when I have a chance of playing is something I'm really looking forward to.
"I've enjoyed playing here against Dundee but I'm looking forward to playing here as a Dundee player. Hopefully I can help the team get to the playoffs and get promoted."
