Lennon, a star performer for Spurs this season, hobbled off in the 2-2 home draw against Basle three weeks ago and has not played since.
The 26-year-old sat out last weekend's 3-1 win over Manchester City after failing a fitness test, but he took part in training with the rest of the Tottenham squad.
His return would be a big boost for Tottenham, who lacked width without the fast winger against last year's champions.
Spurs' injury problems have eased in recent weeks and manager Andre Villas-Boas looks like having almost a full squad to choose from for this weekend's clash at the DW Stadium.
Gareth Bale and Jermain Defoe, who had missed the last few weeks with respective ankle and pelvis problems, both came through the City game unscathed.
Younes Kaboul's comeback was delayed after he suffered a thigh strain in an under-21 match against Manchester United last week, but the defender is having treatment on the injury and Spurs hope he will play again this season.
Midfielder Sandro, who is out for the season with a knee injury, is the only other player who Villas-Boas does not have at his disposal.
