(Reuters) - Arsenal could be without defensive kingpin Laurent Koscielny for Sunday's Premier League trip to North London rivals Tottenham Hotspur, after the centre-back injured his knee in Wednesday's 1-0 win over defending champions Leicester City.

Koscielny, who has already been sidelined with thigh and Achilles injuries this season, jarred his knee in the closing stages of the game but played on till the end after receiving treatment.
