The controversial photo of Trimple, Henry and Jackson
Ireland and Ulster stars Chris Henry and Paddy Jackson have been forced to apologise after being photographed wearing black make up and posing as Ethiopian athletes two years ago.
Both Chris Henry and Paddy Jackson had apparently dressed up for an Olympic-themed fancy dress party.
The African and Caribbean Support Organisation in Northern Ireland said that the photo was deeply offensive.
In a statement, Ulster Rugby said they "apologise unreservedly for any offence."
They added; "It was not the intention of the players to cause upset and the photograph has since been removed."
Andrew Trimble, another Ireland international and Ulster star, and devout Christian, was also pictured wearing black make up with fellow Ulster teammate Michael Allen and former Ulster player Paddy McAllister.
The photo came to light after Jackson posted it on Twitter.
