The winger has been out of action for the last three weesk due to the injury and his return will be a welcome boost for manager Harry Redknapp as he looks to get their bid for a top four finish in the Premier League back on track.
Lennon originally picked up the problem in Spurs' FA Cup clash against Stevenage on March 7, but he has responded well to treatment and is now being tipped for a start against the Swans.
Redknapp has no new injury worries to contend with after the midweek quarter-final victory over Bolton although Ledley King may have to be rested due to his ongoing knee problems.
He told reporters: "We're pretty much okay after Tuesday night. We haven't too many more problems, most came through that game okay, so we're fine."
All stars who definitely won't be involved in the game are long-term absentees Michael Dawson, Heurelho Gomes and Tom Huddlestone.
