Olympique Marseille’s Ghanaian striker Andre Ayew has been ruled out of the French side’s opening Champions League game at Olympiakos on Tuesday.

“Andre Ayew will be out for 10 days after injuring his groin while on international duty,” the Ghana FA said on its website (www.ghanafa.org) on Thursday.

The injury was sustained during a Nations Cup qualifier at home to Swaziland last Friday.

Ayew will also miss Saturday’s league match against Stade Rennes.

Marseille were drawn with Olympiakos, Borussia Dortmund and Arsenal in Group F of the Champions League.
