Ulster hooker Rob Herring has signed a two-year contract extension with the Irish province which will keep him at Kingspan Stadium until 2018.
South African-born Herring made his Ulster debut in August 2012 following a stint with London Irish.
Herring made his Ireland debut against Argentina last year and he captained Ulster during Rory Best's absence during the recent World Cup.
"I'm very happy to be staying," said the 25-year-old.
"The last three years have gone really quickly for me and I've enjoyed every minute of it.
"Captaining Ulster while Rory was away at the World Cup was massive highlight for me and it was a proud moment that I'll remember forever."
Ulster's director of rugby Les Kiss said that he "delighted" at Herring's decision to remain with the Irish province.
"He is highly regarded by his peers and he has developed into one of the key leaders within our group," added Kiss.
"He's still relatively young for a front row player and will develop even more, but to have 79 caps for Ulster at the age of 25 is testament to his quality."
Meanwhile, Munster back-row CJ Stander has signed a two-year contract extension with the club.
South African-born Stander is being tipped for a call to the Ireland squad for the Six Nations Championship in the Spring after becoming Irish-qualified following the World Cup.
