Laurent 'Koscielny out for three weeks'

Arsenal look likely to be without defender Laurent Koscielny for three weeks after he limped off injured against Everton on Wednesday night.

Theo Walcott gave the Gunners the lead before Marouane Fellaini levelled for the hosts as the two sides drew 1-1 at Goodison Park.

However, the French defender was replaced by Kieran Gibbs inside four minutes after he suffered what looked to be a groin strain and could now be missing for several weeks, according to manager Arsene Wenger.

"He has a groin strain. That's usually three weeks," said Wenger.

The 27-year-old has appeared 12 times for Arsenal so far this season.
