Ex-Arsenal midfielder Abou Diaby suffers injury in Marseille training

Abou Diaby's much-anticipated debut for Marseille has been put back again after the former Arsenal midfielder picked up a calf injury in training.

Diaby, 29, had looked close to a return to action after being included in Marseille's squad for their Coupe de France tie with lower league Trelissac last month and named on the bench for their 1-1 draw with Saint-Etienne on Feb. 21.

However, Marseille manager Michel confirmed on Wednesday that Diaby would not be fit for Thursday's cup quarter-final at amateur side Granville, with the ex-Auxerre central midfielder suffering yet another setback in his bid to play competitive football for the first time since September 2014.

"Friday morning I said he was on the list -- that he was ready to play," Michel said on Wednesday. "But on Friday afternoon after training he injured himself, so I obviously replaced him.

"People criticised me for [saying he would be in the squad], but he really does have a calf injury."

Diaby joined Marseille last summer following a nine-year stay at Arsenal.

His last appearance was during the Gunners' 2-1 Capital One Cup loss against Southampton in September 2014.
