More NRL rule changes announced, some aim to further increase speed of the game & player fatigue. Was an increase in major injuries (5+ weeks recovery) with rule changes this season, but how much due to short prep time for teams (3 weeks) + COVID challenges?
Some COVID challenges may still exist next season (gameday travel, limited support staff in bubble?), but definitely benefit in announcing changes with 3 months til Round 1 giving teams a chance to prepare/tailor training.
⬆️ in speed/fatigue doesn’t always mean ⬆️ performance or player safety (for a long read see thread below). The key is finding a balance between fatigue & freshness of players. Do the new changes move the balance too far towards fatigue? 2021 injury rates will be very interesting
One rule change directly related to injuries/player safety below. Once again balance key here; want to keep gladiatorial essence of rugby league but don’t want injured players unwilling to be checked due to risk of going off for extended period (particularly possible concussions)
Thinking more about this; whilst it will discourage gamesmanship/holding up the play for non-serious injuries, it may actually result in similar stoppages. Play will have to be stopped while player is removed from the field to be assessed, sometimes that isn’t safe straight away

Plenty of discussion about reducing the interchange with reference to injury rates, fatigue and “bringing back the little man”. Wanted to discuss what evidence suggests a reduction in interchange would do to injury prevalence (spoiler: it’s not set in stone). Thread ⬇️
There’s 2 main schools of thought:
- Increased interchange = ⬆️ speed & power of players, ⬆️ collision forces so traumatic injury rates ⬆️
- Decreased interchange = ⬆️ fatigue, players exposed to risk events when fatigued, decision making impaired, ⬆️ soft tissue strain rates
In 2001 the NRL went from unlimited to 12 interchanges. Evidence at 1 club showed:
- A significant ⬇️ in players leaving the field due to injury
- But this ⬇️ didnt lead to signifificant change in number of players who were injured & unable to return to the field
