Arsenal midfielder Aaron Ramsey is reportedly likely to be sidelined for one month with a hamstring injury.
The Wales international went to ground clutching the back of his right leg early in the second half of Arsenal's shock 2-0 victory over Bayern Munich in the Champions League on Tuesday night.
Manager Arsene Wenger confirmed after the match at the Emirates that Ramsey will play no part in this weekend's Premier League game against Everton.
According to the Daily Mail, the North London club are yet to discover the full extent of the Welshman's injury due to large swelling around the muscle, but they fear that a one-month layoff is likely.
Last season, Ramsey spent 11 weeks overall out of action with hamstring problems, but a new training regime seemed to have kept the issues at bay until Tuesday night's injury.
