The Roosters' chances of clinching the premiership will depend on Sam Walker's ankle after the standout halfback was forced to leave the field during their match against the Dolphins.
Walker received assistance from trainers after sustaining an awkward left ankle injury in a tackle by Dolphins player Kulikefu Finefeuiaki during the Roosters' 26-12 defeat at Allianz Stadium.
This tackle did not draw a penalty for a hip-drop, but it could turn out to be a pivotal moment if the talented playmaker faces serious injury.
The young Maroons representative will undergo scans to assess the extent of the injury, while the Roosters hope for minimal damage as finals begin in two weeks.
Reports suggest that Walker may be dealing with a syndesmosis injury, which is a tough setback for the player, who could attract significant offers when free agency opens on November 1.
With back-to-back home losses, the Roosters are in dire need of Walker's presence to secure a top-four finish.
If Walker is sidelined for an extended period, Hugo Savala will step in as his replacement, partnering veteran Daly Cherry-Evans for the finals.
The Roosters are also looking forward to the return of try scorer Daniel Tupou, who is recovering from a shoulder injury, allowing Billy Smith to shift to left centre in place of Savala.
Additionally, there could be worries about NSW hooker Reece Robson, who left the game in the final minute.
