Forward Joshua King will return to the Premier League after being signed by Everton.
The Toffees announced the move just after 1 am [UK time] following the filing of deal sheets ahead of the deadline, with King signing until the end of the season for what the club called "a nominal fee".
The Norway international, who joined Bournemouth from Blackburn Rovers prior to the 2015/16 season, scored 48 goals in 161 Premier League appearances for the Cherries before their relegation last season.
Earlier in the day, goalkeeper Jonas Lossl returned to his first club FC Midtjylland without ever playing a competitive game for Everton.
The Toffees also sent defender Jonjoe Kenny and midfielder Anthony Gordon out on loan to Celtic and Preston respectively.
