West Ham attacker Jarrod Bowen could miss this weekend's meeting with Nottingham Forest at the London Stadium.
The 26-year-old suffered a late injury during the 2-0 defeat to Tottenham in north London following a hefty challenge late on in the game. Bowen was not subbed off but he was moving in what appeared to be significant discomfort.
After the game, Moyes said he did not know the exact nature of the issue, or how long he will be absent. But he could well miss Saturday's game against the Reds, which kicks off at 3pm.
