Northampton back-row Roger Wilson is returing to Ulster next season on a three-year deal.
The number eight, who won his only Ireland cap in 2005, made his Ulster debut in 2003 before moving to the Saints five years later.
"It was always in the back of my mind that I would like to finish my career at Ulster," said the 30-year-old.
"I was born and raised there, learned my rugby there and it is home. I'm delighted to be coming back."
Wilson has appeared more than 100 times for Northampton and played against Ulster in last season's Heineken Cup.
"I've really enjoyed my time at Northampton and the club have been very good to me," added Wilson.
"The last couple of seasons have shown that Ulster are a club that can compete to win things.
"They are now considered one of the top European teams and that they're genuine contenders for silverware.
"Ulster have a lot of strength and depth in the squad now, particularly in the back row.
"They don't just rely on picking a strong first XV but have excellent players who can back up those who are starting a particular game and can make an impact from the bench.
"That is a very important thing for a squad. It keeps everyone competing for places and ensures no-one is complacent."
