He now faces a race to be fit in time for the game against the Blues.
Wenger will be keen to have the 30-year-old, who has been his captain and a solid performer during their recent run of good form, available.
If Mertesacker doesn’t make it, Brazilian defender Gabriel is likely to partner Laurent Koscielny at the heart of the Gunners’ defence.
The Frenchman also confirmed that midfielders Alex Oxlade-Chamberlain and Mikel Arteta are still absent through injury.
Skipper Arteta is now close to a return, but Wenger says is still a little bit short of fitness for this weekend.
