Arsene Wenger has eased fears over Tomas Rosicky's latest injury troubles.
The French tactician chose to leave Rosicky in North London after the Czech Republic international picked up a groin problem in Saturday's encounter against Manchester United.
There were concerns that the 27-year-old could be set for a further spell on the sidelines following a fragmented spell of appearances since his move from Borussia Dortmund in 2006.
However, a scan has revealed that the injury is a minor problem, and Rosicky should be in contention for Monday's trip to Reading.
"We feel he will be fit for Monday. He had a scan today [Tuesday] and it came back clear," Wenger explained.
"It is a minor, minor, minor problem, we hope so."
Wenger expressed his concern at Rosicky's current injury proneness, and admitted that the Arsenal coaching staff are none the wiser as to why he keeps picking up muscle problems.
"We think what is happening with him is never big problems, they are small ones," he added.
"At the moment, he is more prone to muscular problems but we have not found the real reason.
"You could see when he's fit he's a very important player to us, but when he comes back from injury it takes him two or three games to get back to his best, so it is vital for him and for us that we sort out his muscular problem.
"I do not think it is linked with the training regime. It is true it is intense but because he is a very genuine player on the pitch he plays always a bit like an engine that turns at 6,000rpm. He always plays to the maximum."
