Arsenal's Aaron Ramsey faces at least one month on the sidelines due to a hamstring injury, The Mail report.
Ramsey picked up the injury in the Champions League win over Bayern Munich and was substituted off in the second half with the game goalless.
Arsenal boss Arsene Wenger told the club's official website after the game he knew the injury would at least keep him out this weekend against Everton.
His injury is a blow to the Gunners with tough games coming up, and he is expected to miss the North London derby with Tottenham Hotspur.
If the prognosis that Ramsey will be out for a month is correct, then the earliest he could even hope to return would be after the international break for the November 21 fixture against West Brom.
As well as this weekend's away trip to Everton, Ramsey will be out for the away game at Swansea City, and the return match with Bayern Munich at the Allianz Arena.
In between is the trip to Hillsborough to face Sheffield Wednesday in the Capital One Cup, before the home fixture against Arsenal on November 9th.
It is a tough run of games for Arsenal to be without the popular midfielder, already without the sidelined Jack Wilshere who is not expected back until December.
