Cian Healy has signed a new three-year contract with the Irish Rugby Football Union (IRFU) and Leinster.
There were concerns over the 28-year-old's future in the province when his name was absent from a list of 17 contract renewals announced by Leinster on Tuesday.
However, amid reports he could be set for a move to the Premiership, Healy has agreed a new deal that will keep him in Ireland until the end of the Rugby World Cup in 2019.
The prop has been plagued by injuries in recent years and, after undergoing knee surgery in January, is yet to make an appearance at the 2016 Six Nations.
Healy - a two-time Six Nations winner with Ireland - is nearing a return and is pleased to have secured his future.
"I feel that I am coming back to full fitness now and would like to thank the medical and S&C [strength and conditioning] teams for their ongoing support," Healy said in a statement.
"There are a lot of exciting young talented players coming through at Leinster and Ireland and I am looking forward to competing for silverware over the next few seasons."
Since making his senior debut for Leinster in 2007, Healy has made 148 appearances for the province and 56 caps for Ireland.
