Enner Valencia: West Ham striker injured in 'broken cup' accident
West Ham striker Enner Valencia is likely to miss Saturday's Premier League match against Arsenal after cutting his toe on a broken cup.
"He had an accident at home and has cut his big toe quite severely," Hammers manager Sam Allardyce said. "It has been stitched.
"We think it will be too soon for him be considered for the game at Arsenal."
BBC Sport understands the injury is likely to keep Valencia out for between two and three weeks.
West Ham described the injury on their website as a "deep laceration".
Ecuador international Valencia, 25, has scored four league goals this season.
Allardyce, who already has striker Andy Carroll sidelined for the season with a knee problem, said: "It was a freak accident at a time when we could have done without it due to our lack of available strikers.
"Our lack of goal scoring power is a worry. Not having alternatives to use is concerning going into the last 10 games."
West Ham have failed to win in their last seven matches, scoring just four goals in the process.
