Former Flying Eagles midfielder, Michael Olaitan, has returned to action after more than 10 months on the sidelines, africanFootball.com reports.
The midfielder made a substitute return for Olympiacos in their 3-0 win over Tyrnavos in the first leg, third round Greek Cup game.
Michael Olaitan experienced the problem when he fell to the ground unchallenged playing for Olympiacos during a league game against Panathinaikos on March 2, 2014.
Michael Olaitan had to visit a top cardiologist in Belgium before he was given the all-clear to return to the field.
