Dan Tuohy has agreed a contract extension to remain at until until June 2015.
The 27-year-old joined the province ahead of the 2009/10 season from Exeter Chiefs and has amassed 74 caps in just over three seasons and was a member of the side that contested last season’s Heineken Cup final.
To date, the player has amassed five caps for Ireland with his first start coming against New Zealand in June of this year.
"The club has made a dramatic transformation in the short time that I’ve been here and it’s fantastic to be part of" - Dan Tuohy
Commenting on his Ulster career to date and his ambitions for the next three seasons, Tuohy said:
“I came over here four years ago and settled immediately. I feel very comfortable here and it’s like a home from home for me. Ulster has looked after me really well and I’m delighted to be staying on.
"The club has made a dramatic transformation in the short time that I’ve been here and it’s fantastic to be part of.
“We did well last year in the Heineken Cup and are hoping to go one better this season. We also realise how important the PRO12 is and we are determined to be successful in it too.
"It’s something I really want to be part of and I never really thought about leaving. There would have been a lot of unfinished business if I had left so that never even entered my mind. I’m thoroughly looking forward to helping Ulster be successful over the next few years.”
