Cave is a graduate of the Abbey Insurance Ulster Academy and he made his senior provincial debut as a replacement in the 9-33 win over Border Reivers in April 2007. He is currently Ulster’s third most-capped player, having made 208 appearances, and has scored 44 tries.
The 31-year-old also has 11 international caps to his name and was a member of Ireland’s 2015 World Cup squad.
Commenting on his new deal, Cave said:
“I’m really pleased to be staying on for another season. This month marks 11 years since I earned my first Ulster cap and I still feel that I have much more to give.
“We have a lot of work to do but the guys are committed to improving as individuals and as a collective. Hopefully we can finish this season strongly and then bring that through to the new campaign.
“I believe the future of Ulster Rugby is bright and I’m really looking forward to being part of that.”
Operations Director, Bryn Cunningham, welcomed the news:
“Darren has been an integral part of Ulster Rugby for over a decade and he still has a lot to offer both on and off the pitch.
“He is proud to represent Ulster and gives absolutely everything to the cause every time he pulls on the jersey.
“He’s a very intelligent player who has an excellent understanding of the game and he communicates superbly with others. He provides a different threat to our other centres in attack and he is also a very astute defender, which he has proven time and time again.
“In addition to what he adds on the pitch, he is a really good role model and mentor for younger players in the team. We are losing a few senior players at the end of this season and therefore it’s particularly important that we keep hold of guys like Cavey.”
