The Spurs captain could be in contention to make an appearance at Wolves on Saturday in the Premier League as he returns from his latest knee injury
The 30-year-old defender missed the whole of pre-season after undergoing knee surgery in July but has slowly been working his way back to fitness.
He had been expected to feature for the reserves at Kettering on Wednesday night but the club instead staged a behind-closed-doors training match yesterday.
King could now be available for the first-team as early as Saturday, when Harry Redknapp's side travel to Wolves in the Premier League.
The England international's return from injury is a boost for Spurs manager Redknapp, who tried to sign Bolton centre-back Gary Cahill last week to plug a leaky defence that has conceded eight goals in two league outings this season.
King has been troubled by chronic knee problems throughout his career and only managed nine appearances last season and played the final two games following a seven-month lay-off.
He struggles to play more than once a week because of the injury, which also means he is unable to train with the rest of the squad much of the time.
Redknapp has described him as “a freak” for the way he is able to slot into the Spurs side and perform at a high level despite his injury troubles.
Spurs defender Michael Dawson has been handed the skipper's armband this season in light of King's time on the sidelines, but the 30 year-old retains his status as club captain
