Arsenal are hopeful David Luiz will be able to play again this season.
Mikel Arteta was originally pessimistic about Luiz's injury after he limped off in the 2-0 win over Newcastle United on Sunday.
However, the Daily Mail reports that the injury is not said to be serious.
There is a feeling now that the 34-year-old can play a role in Arsenal's run-in.
The Gunners can reach the Europa League final if they overcome a 2-1 deficit against Villarreal in north London on Thursday.
