West Ham captain Jarrod Bowen is set for a spell on the sidelines after suffering a fractured left foot in Sunday's Premier League game against Liverpool.
The 28-year-old England forward said he sustained the injury in the first half but tried to play on.
Bowen eventually limped off and was replaced by Crysencio Summerville after 60 minutes as West Ham fell to a 5-0 home defeat by the league leaders.
"Unfortunately, in the first half of our game on Sunday I suffered a fracture to a bone in my foot," he wrote on Instagram.
"As always I tried to fight on and continue playing until I physically couldn't.
"Injuries happen in football, but I'm already looking forward to getting back out there as soon as possible. See you all soon."
Bowen is West Ham's top scorer in the league this season with five goals and has four assists.
The club have given no timescale for his return, but said the injury "will sideline the Hammers captain heading into the New Year".
Bowen's setback is a blow for under-pressure manager Julen Lopetegui, with the club 13th in the Premier League - eight points above the relegation zone.
West Ham travel to Manchester City in the league on Saturday.
