Laurent Koscielny is a major doubt for Tuesday night’s game against Swansea after suffering a calf strain during the Chelsea defeat.

The Guardian is reporting the injury in tomorrow’s edition, and his absence would open the door for captain Thomas Vermaelen to make a return to the starting line-up.

It’s another injury worry that Arsenal could do without, however. With central defensive options limited, it leaves Arsene Wenger’s squad skating on defensive thin ice, although some will say they already fell through at Stamford Bridge on Saturday.

Koscielny, along with Per Mertesacker, has started 42 games for the Gunners this season, and was recently left out of the French team because of a hamstring complaint.

There may be worries that lack of rest, or being overplayed, is beginning to take its toll, and with the manager cancelling his regular pre-game press conference tomorrow, we’ll have to wait for the quotes provided by the Arsenal press office tomorrow regarding the fitness and availability of players for Tuesday.
