Everton fullback Leighton Baines will miss the final two Premier League matches of the season after undergoing ankle surgery.
The former Wigan Athletic man limped off injured during last weekend's 2-0 defeat to Sunderland at Goodison Park.
It was confirmed earlier this week that Baines would see a specialist to determine the extent of the injury.
Manager Roberto Martinez confirmed ahead of the trip to West Ham that Baines struggled with the issue for the past three years and has undergone a procedure to correct the problem.
