Everton have allowed defender Brendan Galloway to leave the club and join West Brom on loan for the season.
The left-back joins on a season-long deal to become the Baggies second summer signing, the Toffees have confirmed.
West Brom boss Tony Pulis has been hunting a left-back after Chris Brunt was injured in March and was forced to play Jonny Evans out of position.
Galloway, 20, has made 21 appearances for the Toffees since joining from MK Dons in 2014 but is yet to play this season and his last game came in a January FA Cup win over Carlisle.
Everton beat the Baggies 2-1 in the Premier League on Saturday with Galloway failing to make the squad.
He could make his West Brom debut when they travel to Northampton in the EFL Cup on Tuesday should Albion receive clearance in time.
