Liverpool striker Andy Carroll has passed his medical with West Ham ahead of his proposed ?15million move to Upton Park.
The England international spent last season on loan with the Hammers, where he scored seven goals in 24 games.
After revealing earlier in the day that the forward was due to undergo a medical on Wednesday, Hammers chairman David Gold wrote on his social media account: "We managed to bring Andy's medical forward to this evening and I am delighted to inform you that he has passed with flying colours."
Carroll had been suffering from a heel problem which forced him to miss the recent England friendlies with Republic of Ireland and Brazil, and there were fears he could be out of action for up to four months.
But West Ham boss Sam Allardyce revealed at the weekend a deal to bring the player to east London on a permanent contract was close.
And the 24-year-old is expected to secure a six-year contract, with Liverpool receiving around ?15m for the player.
