West Ham United winger Grady Diangana will stay on loan at West Bromwich Albion until the summer, after the two clubs reached an agreement.
Following speculation that the Hammers might recall him in January, Diangana, 21, will now see out the original season-long deal he signed in August.
He was sidelined with a new hamstring injury during Monday's loss to Stoke.
But Albion head coach Slaven Bilic told BBC WM: "This injury did not change our opinion. It's great he's staying."
Diangana limped off just four minutes into Albion's 1-0 defeat by the Potters - only the Championship leaders' third loss of the season.
Newly appointed West Ham boss David Moyes then reportedly hinted that the Premier League side could recall him.

But Bilic is aware of the importance of England Under-21 international Diangana, who was born in the Democratic Republic of Congo before moving to London, aged four.
Apart from scoring five goals in an Albion shirt this season, he has contributed five assists - and only one of those three Albion league defeats have occurred with him actually on the park.
The game against Stoke was only Diangana's second start in the Albion team after missing five matches with a back injury.
And, in the seven games the Baggies have played since his injury woes began in the 3-2 win at Birmingham City, Bilic's men have won just one of them.
"He is staying until the end of the season at least," added Bilic. "It is something that we have been trying to get done for the last six to eight weeks (prior to previous West Ham manager Manuel Pellegrini's sacking).
"We are so happy but what is very important is that it was what wanted too. Big time.
"Now it is a matter of getting him back as soon as possible. It is not going to be days, but it is not going to be months either. Hopefully only a few weeks.
"The important thing is to get him back for the crucial stage of the season."
Prior to his latest injury, Diangana was already excluded from Saturday's fourth-round FA Cup-tie with parent club West Ham at the London Stadium.
Albion then go to Cardiff City next Tuesday night before a punishing schedule of seven Championship games in 29 days in February.
