West Ham midfielder Declan Rice is out for around a month and potentially longer after suffering a knee injury.
David Moyes' side have hopes of finishing in the Champions League places but the England international's injury puts that at risk, as well as the 22-year-old's chance of making the Euro 2020 championships.
Rice suffered the injury during England's win over Poland in the recent international break, and there is a chance that he will need surgery to resolve the problem, but he could be out for six weeks.
