Arsenal fear Aaron Ramsey could be ruled out for up to six weeks with a hamstring injury, reports The Sun.
The midfielder hobbled out of Arsenal's Premier League clash against Tottenham Hotspur at the weekend. Arsenal drew the game 1-1 thanks to an Alex Oxlade-Chamberlain equaliser, but injuries were the main talking point after the game.
Arsene Wenger will have to wait 48 hours to find out the true extent of Ramsey's hamstring injury, but the report suggests that early assessments from Arsenal's medical staff have delivered bad news.
Ramsey has already been ruled out of next week's games against Galatasaray and Chelsea but a month out would also see him miss another crucial game against Manchester United.
The Gunners are facing up to what is fast becoming a traditional injury crisis. Mikel Arteta was also forced off during the first half of the Spurs game with a calf injury and is also expected to miss Arsenal's next two games.
Jack Wilshere, who played through the pain barrier with a twisted ankle, is a doubt for Chelsea but is expected to miss Galatasaray. The three midfielders leave Arsenal short of numbers in the centre of the park and adds to a deepening problem.
Wenger can lament the fact that Arsenal are getting injuries in their most vulnerable positions with defensive and midfield reinforcements appearing in short supply. However, Arsenal are still suffering injuries across the entire team.
Olivier Giroud and Theo Walcott are both long-term absentees up front while Mathieu Debuchy and Nacho Monreal are out at the back. One more injury in defence will leave Wenger turning to academy players.
Ramsey will be a significant loss for the Gunners as his energy in midfield got them out of trouble time and again last season. His injury record has been troublesome after breaking his leg in 2010.
He spent three months on the sidelines with a thigh injury last season, but still finished as Arsenal's player of the season. Arsenal also rewarded his fine form with a long-term £100,000-a-week contract.
Arsenal take on Galatasaray on Wednesday in the Champions League and will be looking for at least a win after losing 2-0 to Borussia Dortmund in their opening group game.
