Striker Percy Tau has agreed a permanent move to Egyptian club Al Ahly on undisclosed terms.
The transfer will be formally concluded once the transfer window reopens in Egypt and is also subject to international clearance.
The 27-year-old South African international joined Albion in 2018 and had successful loan spells with three Belgian clubs – Royale Union Saint-Gilloise, Club Brugge and Anderlecht – before returning to the club in January.
Tau made six appearances for Albion, making his debut in the FA Cup tie against Newport County in January.
He made his Premier League debut in the 1-0 defeat against champions Manchester City.
Head coach Graham Potter said, “I have really enjoyed working with Percy. He is very professional and extremely popular with the rest of the squad, but at this stage of his career he wants to be playing regularly and we fully understand that.
“This move gives him the opportunity to do that and he is joining one of Africa’s top clubs. On behalf of everyone at the club I wish him well for the future.”
