The Thrylos player caved in as his team surrendered their 26 games unbeaten run to Yannis Anastasiou's Panathinaikos at the Georgios Karaiskakis Stadium 11 days ago.
He fell to the ground unchallenged during the first half and received medical attention before he was taken off on a stretcher.
On his discharge from hospital, Olaitan expressed his gratitude for all who showed their support in his time of travail.
"Thank goodness, finally this difficult week is over. I am blessed, because in all this time I never felt alone," Olaitan posted on his Facebook page.
