Goalkeeper Adrian will miss West Ham’s visit of Swansea and their other two remaining games of the season because of a calf injury.
The 29-year-old stopper has missed only three games for the Hammers in the Premier League this season, but has been ruled out of the Swans’ visit to Upton Park on Saturday.
Manager Slaven Bilic revealed Adrian sustained the issue following West Ham’s 3-0 win at West Brom, and does not expect him to feature again this season.
Darren Randolph, the Ireland international who impressed in West Ham’s run to the last eight of the FA Cup this term, will deputise for the stricken Adrian.
“Adrian is injured,” Bilic said. “He felt his calf after the West Brom game and reported it to me.
“It’s minor but unfortunately because it’s his calf. He is out against Swansea and probably for the rest of the season.
“We have a great deputy in Randolph when we’ve needed him. Whenever he has stepped in he’s been brilliant.
“He’s one of the reasons we went far in the FA Cup. He was great against Manchester United, home and away, and Liverpool. We’re happy to have him.”
Bilic has an otherwise fully fit squad to pick from as his side look to keep alive their hopes of qualifying for Europe with a win against Swansea.
The Hammers currently sit in sixth spot, five points behind fourth-placed Manchester City but with a game in hand.
