Andy Carroll will complete his transfer to West Ham United today after passing a medical with the Barclays Premier League club.
The 24-year-old striker, who spent last season on loan at Upton Park from Liverpool, had been due to undergo an assessment today.
But last night Hammers chairman David Gold revealed the examination had already been completed.

Gold tweeted: "We managed to bring Andy's medical forward to this evening and I am delighted to informed (sic) you that he has passed with flying colours."
Carroll passed the tests despite a heel injury suffered towards the end of last season, which could see him miss the start of the new campaign.
With the medical complete, Carroll will now complete the £15 million move and sign a six-year, £100,000 a week contract.
That means, including his loan spell, West Ham are committing to spend £55.9m on a player Liverpool bought for £35m in January 2011.
Carroll scored seven goals and added four assists in 26 league appearances for the Hammers last season after struggling at Anfield under Kenny Dalglish.
Dalglish's replacement, Brendan Rodgers, could not guarantee Carroll regular game-time and the strapping striker's aerial prowess conflicts with Rodgers' passing game.
Rodgers is keen to bring in funds to help his own summer spending, with Shakhtar Donetsk's £20million-rated forward Henrikh Mkhitaryan, Sporting Lisbon defender Tiago Ilori, Sevilla midfielder Luis Alberto and Sunderland goalkeeper Simon Mignolet all on the radar.
