The Gunners had feared that the 24-year-old Belgium international was facing a lengthy period out of action, although Vermaelen is likely to miss the showdown with Manchester United this weekend.
Meanwhile, Eduardo will miss the clash with the Red Devils due to a hamstring problem, but Emmanuel Eboue and Alex Song are back in contention after returning from the Africa Cup of Nations.
Boss Arsene Wenger told the club's official website: "There is no fracture in Thomas' leg, but his injury still has to be assessed. There is still a good chance he will not play on Sunday.
"Eduardo has a small, small, hamstring problem. He will be out for one week. He will not make Man United, but he might make Chelsea.
"However Emmanuel Eboue and Alex Song have been in this morning. Eboue has been running outside.
"They are both in good shape, tired but in good shape. Both of them are available for Sunday."
