Smith might have toured the Dolphins' facilities, as well as those at the Cowboys and Dolphins, but he is set to link up with the Roosters from 2023, while Mahoney is heading to Belmore to ink a four-year contract with the Canterbury Bulldogs.
It's Smith's arrival at the Roosters which has the Dolphins interested however.
Smith's arrival means Verrills is likely to be relegated to the back up role on the bench for the Roosters from 2023, and while he is on contract at Bondi for Smith's first season at the club, provided the deal does get confirmed, he is free to explore his options after that.
With Freddy Lussick and Ben Marschke also in Trent Robinson's side, he isn't short of back ups for the 80-minute Smith, and it could yet make sense for the tri-colours to free Verrills for a move before the end of his current deal.
The report suggests he is the club's number one target when it comes to finding a number nine for 2023, and while Harry Grant is still on the radar for 2024, Verrills' signature going to the Dolphins could completely change that.
It's understood Wayne Bennett is a fan of the youngster, with reports the Eels are also chasing him following Mahoney's move to Belmore.
The Dolphins have only managed two signatures since November 1 amid a slew of players they have missed out on, with Felise Kaufusi and Ray Stone their only two additions to an otherwise blank roster at this stage.
