The 24-year-old Romanian international has been out of action since the end of January.
"Vlad has been out for a while and we have to make sure we take our time with him," Spurs boss Tim Sherwood told the club's official website.
"We're pleased to see him back in training this week and we're looking to drop him back into Friday's Under-21 game against Arsenal at the Lane.
"He's trained well and he hasn't felt any reaction to his back, so we're well pleased with that."
Tottenham are back in action on Saturday when they make the trip to Liverpool in the Premier League.
