West Ham United manager Slaven Bilic has confirmed that defender James Collins will miss the next three games with a hamstring injury.
The 32-year-old suffered the problem during Wednesday night's 1-0 victory over Tottenham Hotspur at Upton Park.
The Hammers are in the chase for a Champions League spot as they are currently one point behind fourth-placed Manchester City, but their campaign will continue without Collins.
"It's not one week or a few days, but it looks like he will miss three games," Bilic told reporters in Friday's press conference. "That is a big blow because he has been marvellous."
West Ham will take on Everton at Goodison Park on Saturday.
