Tottenham Hotspur midfielder Etienne Capoue is out for a month after suffering a sprained ankle in the north London derby against Arsenal.
The Frenchman was stretchered off in the second half with his left leg in a brace after receiving lengthy treatment, which included oxygen and being treated for shock following a challenge from Gunners playmaker Santi Cazorla.
Manager Andre Villas-Boas had originally feared that Capoue, who joined the club from Toulouse in August, could be a long-term injury victim but Tottenham have confirmed that following a scan on Monday the 25 year old will be out for just four weeks.
"Etienne Capoue has this morning (Monday) undergone an MR scan which has revealed the midfielder suffered an ankle sprain against Arsenal on Sunday," a Tottenham statement read.
"The recent signing from Toulouse was injured after 72 minutes at the Emirates Stadium and was immediately taken to hospital to consult with a Foot and Ankle specialist. Early indications suggest the France international will be unavailable for a period of four weeks."
Villas-Boas said on Sunday: "He's being ex-rayed now, it doesn't look to go so we'll just have to wait for a bit more information."
Capoue has been withdrawn from the France squad for the World Cup qualifying double-header against Georgia and Belarus but despite the international break will miss four games for Spurs during his four-week lay-off.
He will be absent for the visit of Norwich City on 14 September and the trip to Cardiff City in the Premier League which sandwiches their Europa League opener against Tromso, while the League Cup tie against Aston Villa is likely to come too soon also.
However, Capoue is expected to be fit for the home game against Chelsea on 28 September.
Capoue was one of seven summer signings made by Villas-Boas this summer to offset the departure of Gareth Bale, who joined Real Madrid for a reported world-record fee.
However, Tottenham's new faces were unable to gel sufficiently in order to fend off Arsenal at the Emirates Stadium at the weekend, as Olivier Giroud's goal secured a much-needed victory for Arsene Wenger's side.
