"It's coming on great actually," Redknapp told Spurs' official website.
"Obviously, when I first found out about the stress fracture it was a little bit disappointing.
"Now, it's been five weeks and I've come out of the after-cast, I should be back playing in hopefully about three weeks.
"Within the next ten days I should be back training with the lads, which is good.
"After the Villa game we haven't got a game for a bit so I shouldn't miss too many more."
