The 27-year-old Australian is currently on a season-long loan from Castleford, but is set to stay with the Red Devils after the two clubs agreed a deal. Wigan were thought to be showing interest in Carney and Salford say they have beaten off competition from a host of rival clubs for his signature on a contract until the end of 2019.
Carney – known as the Tank on the Flank – was a big fans’ favourite at Castleford, where he scored 63 tries in 62 appearances, but his career was thrown into jeopardy towards the end of last season following allegations concerning his private life.
Carney’s stay at the Jungle became untenable and, after weeks of uncertainty, he was thrown a lifeline by Salford owner Marwan Koukash.
He has scored six tries in 12 Super League appearances so far for the Red Devils, including two against Castleford in their 32-16 First Utility Super League win at the Jungle in March.
Salford – including Carney – will travel to Castleford for a BBC-televised Ladbrokes Challenge Cup sixth-round tie on Saturday, May 7.
In a statement, Castleford said: “Castleford Tigers can confirm that Justin Carney’s request to be released from his contract has been accepted.
“The release will happen on June 1 and Carney will remain on loan at Salford Red Devils until then.
“Castleford Tigers will make no further comment on this matter.”
Meanwhile, Tigers prop Andy Lynch has been charged with making grade A dangerous contact on James Donaldson in the 56th minute of Hull KR’s win at the Jungle on Sunday. Lynch will not be banned if he submits an early guilty plea.
