West Ham United striker Andy Carroll sustained a foot injury upon his return to training on Monday.
• Thorne: Fresh injury worry
Carroll, who missed 18 of West Ham’s 42 games last season, has not featured for the club this season as a result of a heel problem.
It had been hoped that he would soon be back in action, but he sustained a fresh setback on Monday.
A statement on the club’s official website read: “West Ham United can confirm Andy Carroll suffered an injury to his right foot during his return to full training today.
“Although it is in the same part of his foot as his previous injury, it is a new injury and therefore there will be no prognosis until he has seen a specialist.”
The Hammers will continue to rely on Modibo Maiga and Ricardo Vaz Te to lead the attack, with Carlton Cole’s mooted return to Upton Park failing to come to fruition after he failed a medical.
