Darren Randolph: West Ham re-sign goalkeeper from Middlesbrough
West Ham United have signed Republic of Ireland goalkeeper Darren Randolph from Championship side Middlesbrough for a fee of about £4m.
Randolph made 42 appearances for the Hammers between 2015 and 2017, before moving to Boro in a £5m deal.
The 32-year-old rejoins the London Stadium side on a three-and-a-half-year contract.
"I had no hesitation in coming back," Randolph said. "This opportunity was simply too good to turn down."
Randolph's arrival comes with the Hammers' first-choice goalkeeper Lukasz Fabianski out with a hip injury.
Poland international Fabianski, 34, suffered a reaction when taking a goal-kick during the 1-0 Premier League loss at Sheffield United.
Randolph has not played since 24 November because of a thigh injury, but is expected to be available for Saturday's home league game against Everton (15:00 GMT).
The former Birmingham and Motherwell keeper played in West Ham's final game at Upton Park in 2016 - a pulsating 3-2 win over Manchester United - and their first fixture at London Stadium, a Europa League qualifying win over Slovenian side NK Domzale.
"West Ham is a massive club, with fantastic supporters and an excellent squad of players," Randolph added.
"It's a great challenge for me. I am really looking forward to working with the goalkeepers here and helping the team in any way I can."
