The ex-Northern Ireland shot-stopper made his debut for Harry McConkey&aposs side on their trip to the BMG Arena. However, his return to action didn&apost quite go to plan as he was forced off injured in the first half, with Annagh 1-0 up at the time.
Carroll came into the side with Ballinamallard struggling from an injury crisis, but he had to be replaced by Josh Brownlee, who is some 23 years his junior.
Northern Ireland U17 and U19 manager Gerard Lyttle told BBC Sportsound: “I couldn&apost believe it when I saw it because he is in our staff group chat. Nothing surprises me from Roy. He is a maniac and mad. It&aposs unbelievable, and he will get some stick. He has come on and then had to go off.
“I messaged him saying as long as he wasn&apost sent off.”
Carroll joined United in July 2001, winning the Premier League title with the club in 2003. Carroll was later part of the side that lifted the FA Cup trophy in 2004, but was released by the Reds in May 2005 after he refused to sign a new deal. The club failed to assure him that he would be first choice for the next season.
