West Ham midfielder Cheikhou Kouyate will miss the rest of the season to undergo surgery on an injured wrist.
The 27-year-old has been playing with the problem all season, across 36 appearances in all competitions and three internationals with Senegal at the African Nations Cup.
The decision to have the operation has been taken after West Ham mathematically assured their place in the Premier League next season with a 1-0 win over Tottenham on Friday Night Football.
Kouyate will miss the Hammers' penultimate match against Liverpool at the London Stadium as well as their final day trip to face Burnley at Turf Moor.
Kouyate is contracted at West Ham until 2021 after signing a new long-term contract in March 2016.
He joined the East London side from Anderlecht for £7m in June 2014.
