Having seen off Galway United with an impressive display a few weeks back, the Donegal side were hoping to carry off another giant-killing act.
But it wasn’t to be as Rovers guile and fitness probably proved a little too much for Cockhill.
But the Inishowen men have a huge amount to be proud of with a fine display against Rovers – one of the Eircom Premier League’s best sides.
Indeed Donal O’Brien’s side held Paul Cooke’s outfit to just 1-0 at half time after Joseph Ndo opened the scoring in the 17th minute.
Former League of Ireland star O’Brien said before the game that this was the highlight of his career after spells with Shelbourne, Derry City and Finn Harps.
The well-known Dublin, who is community worker in Buncrana, has done wonders with Celtic.
However on this occasion it wasn’t meant to be as Cockhill conceded another three goals in the second half which saw Rovers go through to the next round.
