MOUSA Dembele has been ruled out of Tottenham's north London derby against Arsenal on Saturday.
The Belgian had hoped to return for Saturday's crunch match at the Emirates Stadium, but manager Andre Villas-Boas today ruled the playmaker out of the game.
"Dembele does not have a chance, not for this game," Villas-Boas said.
"There is a 50% chance he will be back for the Lazio game.
"I think surgery at the moment is out of the question, hopefully."
Lennon appears to have been given the green light to play against the Gunners, but Villas-Boas is unsure whether Defoe and Walker will be available.
"They haven't trained with the team yet. They have had lighter sessions on their own," Villas-Boas said of the trio.
"We will have to see today how they return to see if there's any disturbance.
"Lennon had a scan yesterday, and it's fine on his hamstring."
Villas-Boas is already without long-term absentees Scott Parker, Benoit Assou-Ekotto and Younes Kaboul.
