The 23 year old, who currently plays for Exeter Chiefs, has signed a two year contract with Ulster. Tuohy is due to arrive in the province for 09/10 pre-season training.
The Irish-qualified, Gloucester born Tuohy, stands at 6' 5" tall and 17st 10lbs, and already has Irish U21 honours to his name. Tuohy made his first professional rugby appearance for Gloucester against London Irish in 2007, and received the man of the match award.
Talking about Ulster Rugby's new signing, Ulster Head Coach Matt Williams remarked: "Dan is an impressive young Irish qualified player. He has come through a strong academy system in the Guinness Premiership, and been constantly a first-rate player. He has been on Ulster's radar for a while now, and I am delighted we have finally signed him up."
Ulster Rugby have extended winger Simon Danielli's contract by one year until 2010, and prop Bryan Young gained a two year extension, which will see him play his rugby with Ulster until 2011.
