Tottenham captain Hugo Lloris is a major doubt for the club's first game on their return to the Champions League next month after the club confirmed he will be out for around four weeks with a hamstring injury.
The French goalkeeper was replaced by Dutch stopper Michel Vorm after 35 minutes of the 1-1 draw against Everton on Saturday.
Spurs' medical staff have set an initial prognosis of four weeks before manager Mauricio Pochettino can select his first-choice keeper again.
He will miss upcoming fixtures against Crystal Palace and Liverpool, while France will also be forced to do without Lloris during the upcoming international period.
