In rugby, HIA means Head Injury Assessment. It’s the process used to check whether a player who may have had a head knock or concussion should be removed from play and monitored further.

Quick Scoop

HIA is mainly used in professional and elite rugby. It combines sideline checks, medical observation, and sometimes video review to help decide whether a player can safely continue or needs concussion management.

How it works

  • A player with a possible head injury is taken off for assessment.
  • Medical staff look for signs of concussion, using tests and observations.
  • In some cases, the player can return only if they pass the assessment within the allowed time window.
  • If concussion is suspected or confirmed, the player is not sent back on immediately.

Why it matters

The whole point of HIA is player safety. World Rugby says the protocol was introduced to improve how head injuries are handled and to make decisions more consistent when concussion is not immediately obvious.

Simple example

If a player takes a hard hit to the head, looks dazed, or shows concussion symptoms, the referee and medical team may send them for HIA instead of guessing on the spot. This helps reduce the risk of a player staying on too long after a head injury.
