Gignac out of Marseille decider

André-Pierre Gignac will miss Olympique de Marseille's decisive UEFA Champions League trip to Borussia Dortmund on Tuesday after being ruled out for the rest of the year with a thigh injury.

The 25-year-old striker was a substitute in OM's 2-1 win at SM Caen on Friday but lasted only 13 minutes after suffering what coach Didier Deschamps called "a sharp adductor pain." Scans have confirmed a tear in his left thigh – on which he only underwent surgery in May – ruling the French international out for between four and six weeks.

Marseille lie second in Group F and three points at Dortmund would guarantee a round of 16 place, as would a draw if Olympiacos FC fail to defeat section winners Arsenal FC in Piraeus.
