World Rugby have acknowledged that Kurt-Lee Arendse's yellow card for a deliberate knock-on against England was incorrect. On Whistle Watch, Nigel Owens explained the crux of the call: the test isn't whether a player used one hand, but whether they had a realistic chance of regathering the ball. Both Owens and Jamie Roberts felt Arendse did, and World Rugby's official position backs that view — the TMO should never have escalated it beyond a knock-on. Owens isn't fully letting the officials off the hook though, describing the incident as a genuine grey area and calling for clearer, more consistent guidance on where deliberate knock-on ends and bad luck begins. For a Bok side that had just gone 17-0 up, the sin-binning was a momentum check that, by World Rugby's own admission, shouldn't have happened.
