Concussion rule change right for NRL: Greenberg

NRL clubs could be docked competition points if they fail to adhere to new concussion laws outlined by head of football Tony Greenberg yesterday.

Under the new rules, a player who could be concussed must be diagnosed by the head trainer, and then, if warranted, assessed by the club's doctor who will run a series of tests to determine if the player is fit to return to the field.

If a concussed player does return to the field, in contravention of the test results, Greenberg said possible sanctions would include the loss of points, substantial fines and the suspension of club personnel.

"This is a very important change in policy and clubs need to understand the gravity of that," Greenberg (pictured) said.

"Rugby league is a very tough sport but player health and welfare is at the forefront of every decision we make. These changes are for the good of the game."
