Leeds hooker Danny Buderus is wanted by his former NRL side Newcastle but will not leave "at Leeds' expense".
The 33-year-old, who has a year left on his Rhinos deal, told the Australian Daily Telegraph: "There is an opportunity to go back.
"There is an offer to play and speak about a role after that, but everyone has to remember that I'm still a Rhino.
"This place has been great for me and I'm not going to leave them if they aren't OK with it," he added.
"I have to pay the situation the respect it deserves. There is some red tape and I have to work through it."
The 33-year-old former Australia captain joined Rhinos from the Knights for the 2009 Super League season.
"It has been tough here," he said. "I was probably bought by a club that didn't need me.
"They had an established hooker in Matt Diskin, a great player, and I had to fight my way in.
"Straight away, I went from being an 80-minute player to being a 40-minute player. That was tough, and I also had injuries.
"There were times I wondered whether or not I had done the right thing but it has probably prolonged my career and given me this opportunity to return if things work out."
Buderus also admitted that the opportunity to develop as a coach at the only other club he has played for was tempting.
"I see a new horizon with the Knights and an opportunity for that place to be special again," he said.
"It is just so exciting for the place, my boyhood club, and to see that happen is fantastic.
"I just want to be involved with it but not at Leeds' expense."
