Having only played his last game for Ulster a little over two weeks ago, Roger Wilson has agreed to join Instonians as a player/coach next season.
The province's most capped player, who also had a four year spell with Northampton in the Aviva Premiership, has plans to move to America in the next year but in the interim will be helping the Shaw's Bridge outfit with their aim of returning to the senior ranks.
"This is a new stage of my career but a very exciting one," said the number 8.
"I am interested in developing my skills in the coaching arena and am pleased to be doing that with a club that has the ambition to achieve All-Ireland status.
"Instonians is a club that is full of history and whilst there remains some building and fine-tuning to be done, there is no doubt in my mind that it can reach the target of being a senior club once again."
He will not be the only big name addition for the south Belfast side next season, with prop John Andress also joining up having recently left the professional ranks.
The Belfast-born 33-year-old, who forged a successful career in England with the likes of Exeter and Harlequins, retired last season after a short spell with Connacht.
"To have players of this experience and this calibre joining Instonians is a real coup," commented Director of Rugby Wilbur Leacock. "It is a statement of intent; this is a club with ambition and we have not lived up to our potential for the last three seasons."
