West Ham United midfielder Tomáš Souček will be forced to miss Friday night’s Premier League trip to Luton Town as he recovers from the head injury he sustained in last weekend’s victory at Brighton & Hove Albion.
Souček had to be substituted in the first half of the 3-1 win at the American Express Stadium, following a collision with Albion goalkeeper Bart Verbruggen.
With the Czech Republic international having suffered a concussion, he will have to sit out the Club’s fourth league assignment of the campaign before he is able to return to action.
Moyes will have the likes of James Ward-Prowse, Edson Álvarez, Lucas Paquetá and Pablo Fornals to choose from in midfield as he aims to stretch his team’s unbeaten start.
“Tomáš Souček is not available from the team who played last week,” the manager explained.
"We are covering the Premier League protocols that are set, regarding his concussion."
Ward-Prowse, meanwhile, has enjoyed a fine start to life in east London. The former Southampton man assisted two goals on debut as the Irons defeated Chelsea 3-1, before opening the scoring in the victory against Brighton by the same scoreline.
Moyes had no doubt that the 28-year-old would settle swiftly at his new Club, having racked up 343 Premier League appearances for the Saints prior to his summer move.
"James has played two really good games and we hope that continues and we see more of the same," Moyes added.
"One of the reasons we brought James Ward-Prowse here is because of his Premier League experience.
"He was the captain of Southampton for a long time and he was a loyal player for them too. He’s settled in really well for us and he goes about his business exactly how you would expect from him.
"He’s created goals and scored a goal, and we’re really pleased with how he’s doing."
