England candidate Jarrod Bowen will have a scan on a heel injury after limping out in clear distress during West Ham's 1-0 defeat on Saturday night.
Bowen was hurt after being caught by Andy Robertson as he shaped to shoot early in the second half and though he tried to continue temporarily, the pain forced him out of the action to be replaced by Said Benrahma.
The 25-year-old, who has featured in West Ham's last 79 Premier League games, must be considered a serious doubt for Thursday's Europa League tie against Sevilla and will hope he is not ruled out of a possible first England cap against Switzerland later this month.
