AFC Bournemouth have signed Christian Atsu from Chelsea on a season-long loan deal.
Midfielder Miguel Pallardo has signed a new one-year deal with newly-promoted Hearts while Danny Wilson leaves.
Hibernian signed goalkeeper Sean Murdoch as back-up for Ben Williams ahead of the Clydesdale Bank Premier League clash with Dundee.
The 26-year-old former Dunfermline, Forfar, Hamilton and Accrington Stanley player will be at the club until January after Calum Antell joined East Fife on loan.
Manager Pat Fenlon told the club's official website: "He has been training with the group for the past few weeks and he has impressed us with both his ability and his attitude.
"He will come in and automatically provide us with experienced cover for Ben Williams.
"We felt that it would be beneficial for Calum to get a regular run of first-team games with East Fife. His loan move will give him more experience and help his development."
