Titans' Nathan Friend announces NRL retirement
Gold Coast Titans co-captain Nathan Friend has announced he will retire at season's end after a 15-year NRL career.
The hooker has made 233 appearances in the competition and was an inaugural player for the Titans in 2007.
"I want to take this opportunity to announce my retirement at the end of the 2016 season, from the game I've loved ever since my first encounter as a five-year-old," Friend wrote on Instagram.
"Thanks to everyone that has had a hand in my career I'm forever grateful for the support and guidance I've received."
The Titans, who are 10th in the table, face the New Zealand Warriors on Saturday.
