Canberra's Ricky Stuart is set to sign a three-year extension with the Raiders, according to NRL.com.
An announcement is expected to be made on Monday afternoon, a deal which will tie him to the club until the end of 2023.
Stuart stands as one of the Dally M coach of the year candidates after helping guide Canberra into premiership contention this season.
The new contract will extend his tenure into a 10th season, taking him past three-time premiership winner Tim Sheens as Canberra’s longest serving coach.
The Raiders face Melbourne at AAMI Park in Saturday night's qualifying final, which marks Stuart's second finals campaign at the club.
