William Gallas is likely to be sidelined for three weeks after picking up a groin injury at Blackburn on Sunday.
In the 24th minute at Ewood Park, the Arsenal captain hurdled a challenge from Roque Santa Cruz and went down in agony as he landed on the other side. He immediately called for assistance from the bench and, a few minutes later, hobbled off to be replaced by Philippe Senderos.
"He has done his groin, I knew it straight away," said Arsène Wenger afterwards. "He will be out for three weeks."Copyright 2015 The Arsenal Football Club plc.
