A combative player who can apply himself in midfield or defence, Darragh joined Rovers from the famous Belvedere Football Club of Dublin in the summer of 2011.
Unfortunately his first couple of seasons were blighted by a back injury, but a strong second half to the 2013-14 campaign saw him captain the development squad and named amongst the substitutes for a pair of first team matches.
October 2014 saw the Irishman join League Two side Burton Albion on loan initially for a month. But excellent displays for Jimmy Floyd Hasselbaink's side saw his stay with the Brewers extended until March, playing a huge part in their title-winning campaign.
Recalled by Rovers for the end of season run-in, Lenihan made his debut at Ewood Park as a first half substitute in the win over Millwall in April, with two further starts at the close of the campaign.
On the international stage Darragh has honours for the Republic of Ireland, having represented and captained his country up to Under-21 level.
