Kerr includes Macken in squad to face Bulgaria
The former Preston attacker who was signed by City for £5 million in March 2002 has been cleared by FIFA to play for the Republic of Ireland.
Although Macken had previously played just once for England at U-20 level, he played at no other level for England. Under a change of FIFA rules, players who have not played in a full international game can play for a different country, provided they were entitled to nationality of that country at the time they played at underage level.
