Leeds Rhinos prop Adam Cuthbertson, team-mate Zak Hardaker and St Helens prop Alex Walmsley are the nominees for the 2015 Steve Prescott Man of Steel.
Cuthbertson, 30, and 23-year-old full-back Hardaker helped Leeds retain the Challenge Cup as well as book a top-four place in the Super League.
Walmsley, 25, has been a regular for champions St Helens and is in line for an England call-up this autumn.
The winner will be named on 5 October, with the coach and young player prizes.
Wigan pair Joe Burgess and George Williams, both 20, plus Warrington's Ben Currie, 21, are nominated for the Young Player award.
