Born in Kenourgio, Greece, Darlas began his professional career 1999 in Panetolikos.
In the 2001–02 season Darlas was transferred to Panathinaikos Athens but due to his relative young age (just 19 years old) he was sent on loan to the first Greek division team Kalithea and for the two following years to Markopoulo-based Third Division side F.C.
In the 2004–05 season Darlas went to Apollon Smyrnis before returning to Panathinaikos[1] and made his Champions League debut against Werder Bremen and FC Barcelona.
On 28 June 2010, Darlas signed for French club Stade Brestois 29 for one year with an option for a second.
On 18 July 2012, Darlas returned to Greece and former club Panetolikos, signing a one-year contract.
