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.
The 28-year-old, who joined in July 2010, has struggled with injury during his time at the Riverside and managed 56 appearances.
Only 12 of those came this season, with his last outing coming in the 1-0 defeat Leicester earlier this month.
Elsewhere, teenage striker Jake Fowler has joined Blue Square Bet Premier outfit Stockport on a month's loan.
