West Ham winger Michail Antonio will miss the rest of the season with a hamstring injury, Sky Sports News understands.
The 28-year-old sustained his injury in the opening 10 minutes of the Hammers' 3-0 home victory over Southampton on Saturday and left the pitch in tears.
Antonio, who has scored three goals in 21 appearances for the club this season, underwent a scan on Sunday to determine the extent of the injury and will miss West Ham's final seven matches of the campaign.
Antonio suffered a torn hamstring last April and had surgery to repair the damage.
The Hammers are hoping Manuel Lanzini will be back available for their Premier League match against London rivals Chelsea on Sunday.
Lanzini missed the win over Southampton due to a knee injury he picked up while on international duty with Argentina.
