Super League clubs have been alerted to the availability of Gold Coast pair Anthony Don and Kevin Proctor.
The Titans duo are both off-contract at the end of the season and are open to the possibility of a move to Super League.
Winger Don has spent his entire career with the Titans and has made 130 appearances, scoring a total of 77 tries. The 32-year-old played last week as the Titans picked up their first NRL victory for almost 12 months.
Proctor also featured in that victory, with the club now coached by former St Helens chief Justin Holbrook.
A New Zealand international for the last eight years, the back-rower has made 24 appearances for the Kiwis and featured in their 23-8 victory over Great Britain last year.
Proctor has spent the majority of his career with Melbourne and won the NRL Premiership with them in 2012 before reaching another final in 2016.
The 31-year-old moved to Gold Coast in 2017 and has been a regular ever since.
Both players are represented by Pacific Sports Management, one of the leading agencies in Australia. Their Super League talent includes Kenny Edwards, David Mead and Cheyse Blair.
