Sam Walker paused contract talks with the Sydney Roosters last month.
The reported gap between his management's demands and the club's offer was about $1 million over four years.
He is now 80 minutes from winning a premiership with the Roosters.
Walker overcame a serious ankle injury and played an instrumental role in Friday night's 36-20 preliminary-final win over the Dolphins.
With the Roosters in control late in the match, coach Trent Robinson gave his star playmaker an early finish, with Sunday's decider in mind.
