The England international lead the line for the Hammers in Saturday's 2-1 victory at Wolverhampton Wanderers in the Premier League.
However, Bowen was forced off just nine minutes in the second-half following an innocuous collision with Wolves midfielder Mario Lemina.
Bowen attempted to play on, but it quickly became clear that the attacker was unable to continue and he eventually limped off down the tunnel to receive treatment.
West Ham were trailing at half time after Pablo Sarabia scored the opener for Wolves from the penalty spot, but after Bowen's withdrawal, the Hammers turned the game on its head in the second half thanks to strikes from Lucas Paqueta and James Ward-Prowse.
David Moyes delivers Jarrod Bowen injury updateHammers boss David Moyes has confirmed that Bowen sustained a hip injury against Wolves and is hopeful that the attacker's problem is not as serious as initially feared.
«We've got to hope he's OK. We need all our top players,» Moyes told reporters after the match as quoted by the Evening Standard.
«He's had a knee into his hip or back. It's not a twist. He said he's got kneed and he's really stiff.
»I've had one or two of those myself and they don't go away too quick. I'm hoping it won't be too bad."
West Ham remain seventh in the Premier League table despite their win over Wolves, but they have moved level on points with sixth-placed Manchester United, who play host to leaders Liverpool on Sunday.
