Sanders featured in 23 games, setting up 18 tries, scoring three and forcing nine dropouts.
He averaged 45 metres per match during a strong second half of the season.
News Corp reports the Canberra Raiders have agreed to a new one-year deal with the 22-year-old, though the club has not confirmed it.
Sanders had been contracted through the end of 2027 and recently said he would sign before November 1.
If the deal is finalised, he could become a free agent again on November 1 next year.
He stepped into the No. 7 jersey after Jamal Fogarty left for the Manly Sea Eagles.
Sanders came under pressure from Coby Black, who debuted in the final round and is also contracted until the end of 2028.
The pair could compete for the halfback role and long-term playmaking responsibilities; Black may also be considered at five-eighth if Sanders secures the No. 7 spot.
Ethan Strange currently plays five-eighth, having established himself among the game's best and debuted for NSW in State of Origin this year.
The former Eels junior will aim to build on his form as Canberra seeks to recover from a dismal 2026 after falling from minor premiers in 2025 to missing out in the finals.
