Francis Molo's new Dolphins contract runs through the end of 2028, following a two-year extension.
That agreement contradicts a report from NRL reporter The Mole, who claimed Molo had signed immediately for Leigh Leopards in England's Super League.
"100 per cent not true. I don't know where this incorrect information comes from, but it's not the first time," Rushton told us.
Molo recently represented Samoa in the World Cup, where his performances reinforced the value of the deal, according to the report.
The Dolphins face salary-cap pressure, with Thomas Flegler potentially leaving after 2027. Jack Bostock and Herbie Farnworth have also been linked with the Dragons and Roosters respectively.
Molo is believed to earn about $500,000 annually. If Flegler departs, Molo could take on a larger role in 2028.
The Dolphins signed Molo midway through 2025 after his departure from St George Illawarra in difficult circumstances.
He made 22 appearances for the Dolphins in 2026, averaging 82 metres and recording 443 tackles at almost 97 per cent efficiency.
Molo has played 176 NRL games, including stints with the Broncos and Cowboys before joining the Dragons.
