NRL introduces 18th-man policy for concussion substitutes in wake of horror round of injuries

The NRL plans to introduce a watered-down 18th-man policy, allowing for an injury-replacement player only when a team has lost three men to concussion.

After a weekend of heightened sensitivity regarding player welfare amid more than 20 injuries, the rugby league players' union has called for a replacement player to be granted as a result of the quickened game.

However, the Australian Rugby League Commission only went part way to that on Tuesday, limiting its use from round five on and ensuring the reserve would only be an emerging player.

The proposed rule will be discussed with clubs and the Rugby League Players Association before it is introduced, with the NRL to foot the bill of the extra player.
