Veteran Leeds centre Keith Senior has vowed to keep playing next season, despite the knee injury that has ended his 2011 campaign prematurely.
But the 35-year-old former Great Britain international admits that his future may not be at Headingley.
"I am going to play on next season," he told the Yorkshire Evening Post. "I've still a lot to offer. As to where, that needs to be sorted out."
Meanwhile, props Luke Burgess and Ben Cross have both asked to leave.
Burgess, 24, who is out of contract at the end of the season, has been made available for loan until then, when he is expected seek a move to Australia to join up with brothers Sam and George, both on the books of South Sydney.
The Academy product, who has made 93 appearances since making his debut in 2008, including a Grand Final winner's medal in 2009, has not featured for the last four games.
The 32-year-old Cross has made minimal impact since arriving from Newcastle Knights in the winter and has not figured since the win at Castleford on 29 April.
"Both Luke and Ben have asked the club to be released from the remainder of their contract," said chief executive Gary Hetherington.
"Both have become frustrated that they have not been unable to force their way into the side given the outstanding form of other players in their position and feel the need to move to pastures new to gain first team rugby.
"Luke has indicated that his intention is to move to Australia and play in the NRL. He will be available on loan for the remainder of the season subject to us being able to recall him should injuries to the squad occur.
"We have agreed with Ben's manager that he can talk to other clubs regarding his availability and if he is able to find a club we will agree to his release.
"If he is unable to conclude a deal with another club, Ben is happy to remain at the Rhinos and fight for his place."
Senior, one of only three survivors from the opening campaign in 1996 still going in Super League, underwent major knee surgery a week ago after being hurt in the Rhinos' Challenge Cup win over Harlequins on 20 May.
He is out of contract at the end of the season and has opened talks with Leeds over a new deal but says that other clubs are also showing an interest.
