Antonio was on hand to score a sensational acrobatic effort to give the Hammers the lead, but was withdrawn after 52 minutes with a knock, which Moyes is confident won’t keep him out for too long.
The 57-year-old said he is confident Antonio was just suffering from cramp, hinting that he should be available for West Ham’s next game, which is away at Premier League champions Liverpool on Sunday afternoon.
Antonio has been in excellent form since the resumption of the league last season, scoring seven goals as he almost single-handedly dragged his side clear of the relegation battle, and has added three already this season.
Moyes will be hoping his top scorer can return to full fitness in time to help the Irons continue their impressive recent form, having picked up two points from two tough-looking fixtures against Spurs and Man City, enough to leave them sitting in 12th position after six games.
