Arsenal lose Gallas to injury

LONDON COLNEY, England, Nov 20 (Reuters) Arsenal central defender William Gallas is set to be out for ''a few weeks'' after suffering a thigh injury at the end of training tday, coach Arsene Wenger said.

Wenger, whose side were preparing for tomorrow's Group G Champions League game at home to Hamburg SV, said the Frenchman slipped as he kicked a ball at the end of the session and that his absence would be a blow to their prospects.

Arsenal, who beat Hamburg 2-1 away in a promising start in Group G, have taken only a point from their last two games against CSKA Moscow and are level on seven points with Porto.

With the Russians top on eight points and Hamburg out of the running after four straight defeats, it means Arsenal's campaign will go down to their final match at Porto on December 6.
