Wigan manager Paul Jewell stated: "He's strong, he's aggressive, he's got a finisher's instinct and I think he will add competition in an area where the squad needs bolstering.

[28] Folan suffered a setback during his training program at Birmingham City picking up a nerve injury, which eventually would go on to rule him out of playing football for the good part of a year.

[29] On 1 December 2012, after a lengthy period sidelined due to a previous injury, Folan announced on his official Twitter page that he had joined T-Team in the Malaysia Super League and it was confirmed shortly after.

[2] In March 2007, manager Steve Staunton called on the 'granny rule' to bring Folan into his squad for the UEFA Euro 2008 qualifying campaign, after a passport was issued at the 11th hour.

The decision attracted comment for overlooking other in-form strikers playing outside the Premier League and with closer ties to the Republic of Ireland.

[42] In October 2008, under new manager Giovanni Trapattoni, Folan was one of several uncapped players selected to play for a Republic of Ireland XI in a challenge match against Nottingham Forest, scoring the first goal in a 2–0 win.

[44] He was brought on as a substitute against Italy in the World Cup qualifiers, and set up the equalising goal scored by Robbie Keane in the 87th minute.
