Carroll has been out of action since February after damaging ligaments, which required surgery, and on Friday it was claimed that he would be out for an extra seven to 10 days - until after the international break - following a further mishap, as covered by the Daily Mail.
However, reports suggest that Sevilla are willing to take the striker on a surprise season-long loan; an offer which, amid the Hammers' ongoing injury crisis - with Mauro Zarate and Enner Valencia both sidelined - the club acted swiftly to turn down.
Carroll's return would certainly help to ease the concerns faced by the Upton Park faithful, and on Friday night the Englishman Tweeted the following:
"Training with the lads now so a couple of weeks to get match fit and then I'm back!!"
"It won't be too long before I'm back in my own dream team!! Counting the days!!!"
The England international featured on 14 occasions for the Hammers last term, scoring five goals in the process.
He also fashioned 11 key passes for the club - including one assist - while he won an impressive 118 aerial duels.
Success in 8.43 headers per appearance saw the 6ft 4in forward finish the campaign as the Premier League's most prolific player in this area.
