Tottenham striker Jermain Defoe is set to return to action in Sunday's north London derby at White Hart Lane.

Defoe has been out since limping off with an ankle injury during the win at West Bromwich Albion at the start of February, but manager Andre Villas-Boas indicated that he was considering starting him in place out-of-form Emmanuel Adebayor against Arsenal.
"Jermain trained with the team these last two days, so hopefully he is going to be available for selection," Villas-Boas said.
"Tomorrow [Saturday] he will train once again, and he is definitely a big contender for the team. It is good to have him back."
Villas-Boas acknowledged that a win against the Gunners could be decisive in Tottenham's bid for a top-four finish, but stressed: "I don't think it [the top-four battle] will all be decided on what happens this weekend."
"A seven-point difference if we manage to win is still recoverable for a team like Arsenal. If it comes to a one-point difference, things get closer to us. It's all very tight still.
"We were glad last week to build a difference with Everton to nine points. It's still not enough, but we just have to keep going.
"We are on a good run of form and approach this game in a more confident manner than Arsenal. We had a good month in February, and we want to extend that until mid-April as that will mean we can reach our objectives."
He said it would be "tremendous" for Spurs fans if they could finish above Arsenal, adding: "The rivalry is fantastic. There is a demand to have success in this fixture - it means a lot to everyone in north London. It is a special game.
"We have to play this game with lots of emotion, and emotion will decide this game rather than any tactical preparation."
A defeat to Arsenal towards the end of last season sparked a collapse in form that ultimately cost Tottenham, then managed by Harry Redknapp, a place in the Champions League.
And Villas-Boas said: "I think that serves as an example for these players of what can happen."
