Randolph is no stranger to West Ham since he spent two years at the club after having joined the Hammers back in 2015 as a free agent.
It has been reported that West Ham are interested in signing Darren Randolph from Championship outfit Middlesbrough, but a thigh injury to the Republic of Ireland worldwide goalkeeper has put a hold to that transfer.
Lukasz Fabianski remains sidelined with a thigh injury and David Moyes is eager to bolster his squad by bringing in the 32-year-old keeper.
"This opportunity was simply too good to turn down, though. It's a great feeling to be back in the Premier League with such a fantastic club, and I can't wait to get started".
And as per the latest reports, the Hammers have already agreed on a fee to sign Darren Randolph this month but it looks like the board are hesitant to go ahead with the transfer.
Randolph has been suffering with a thigh injury that has kept him out for three weeks but Boro medics are sure he has fully recovered from the injury, so much so that he was considered for Tuesday night's FA Cup third-round reply defeat at Tottenham.
"I'd like to thank everyone at Middlesbrough - the management, staff, players and fans - for their support. I had a great time there and wish them all the very best for the rest of the season".
Lukasz Fabianski is the first-choice goalkeeper at West Ham, but the 34-year-old Poland global himself is struggling with injury and will be out for a couple of weeks.
