Brian O'Driscoll will reportedly not have an official best man at his wedding tomorrow as a tribute to his tragic best friend.

The Herald claims that the rugby star has decided to have two groomsmen do the honours in memory of his late pal Barry Twomey.

"He hasn’t got a best man, per se, as Barry would have been his best man so he is having two groomsmen instead, who were absolutely delighted to be asked” said a source.

"There will be references to Barry on the day as he is going to be sorely missed by Brian."

Barry, who shared a house with Brian, died tragically in 2008.
