Phoenix Crossland's suspension has created the possibility of an extremely rare first in 90 years at Sunday's grand final, though the nature of the milestone was not specified.
Roosters utility Connor Watson is reportedly pushing to play against Newcastle after suffering a head knock against the Dolphins last Friday.
Watson is due to see an independent neurologist on Thursday as he and the Roosters seek to have his category one HIA reclassified as category two.
His assessment was initially category two, then upgraded to category one after he left the field, angering the Roosters, who reportedly intend to challenge the decision.
Players diagnosed with a category one concussion must sit out for 11 days, although exemptions have been granted before.
Manly's Tolu Koula played eight days after failing a HIA in an Origin match.
Watson, who will join the Dragons next season, is keen to take the field, but neurologist Professor Mark Parsons questioned whether he could be cleared.
"I'd be very surprised if an independent neurologist would clear him. I've seen plenty of NRL players over the years. They'll tell you they are fine, but now we can do neurophysiological tests to give objective evidence of how the brain is functioning," Parsons told the Sydney Morning Herald.
"A lot of expert authorities suggest 11 days isn't long enough when there has been a category one head injury where there has been a loss of consciousness. Looking back at the replays of the incident on Friday night, he definitely got knocked out and lost consciousness."
