Coquelin pulled his hamstring in the first half of the 3-3 draw at Bournemouth on Tuesday, and was set to have a scan on Thursday to determine the full extent of the damage.
The injury comes at a bad time as Arsenal are without Mohamed Elneny for the same period, with the Egyptian away at the African Nation Cup.
It will likely force Granit Xhaka to take on a more defensive role, which could give an opportunity to Aaron Ramsey to play in the second central midfield position normally occupied by Cazorla
