West Brom have mutually agreed with West Ham United that Callum Marshall can return to train with his parent club for the rest of the season.
The 19-year-old Northern Ireland striker signed for Albion on 26 January after scoring 19 goals for the Premier League side's Under-21s this season and making his senior Hammers debut.
But he has had a total of just 55 minutes playing time with Albion.
He was an unused substitute six times and had three outings off the bench.
Marshall, who has not been in the Baggies squad at all for the last three matches, will return to play for West Ham's Premier League Two side, but can still be available for Albion if they want him.
