The Canterbury Bulldogs are reported to be privately seething over the National Rugby League's decision to slap them with a $20,000 fine after Josh Jackson was allowed to remain on the field despite showing signs of concussion.
The Bulldogs are certain to appeal the breach notice handed to them yesterday by the NRL for an incident in the final moments of their second round win over Cronulla when Jackson struggled to get to his feet after making a tackle.
He then got back to take his place in the defensive line without being treated by a member of the Bulldogs' medical team.
A club source said they were upset at the ruling because their physio was already treating another player and unable to attend to the back-rower before the fulltime siren sounded.
27 players have been taken from the field to undergo the newly-introduced Sideline Concussion Assessments in the season's first five rounds, with 14 of them returning to the field after being cleared of concussion.
