“Sure it was [an alert] and I noticed the deal with once more – only a regular deal with,” Townsend mentioned.
“I feel now we have to essentially watch what we’re doing right here. Belief in know-how that is not been confirmed.”

They document the acceleration power (G-force) and path of power concerned in contacts, often called “head acceleration occasions”, and may present real-time knowledge to a health care provider or official on the sidelines.
Fagerson is the second Scotland participant impacted by the brand new know-how after hooker George Hooker went off the sphere for an HIA within the defeat by France.
Townsend added: “What we have been doing over the previous couple of years is ensuring that any signs which can be seen, a lot of folks can flag up whether or not somebody goes off for an HIA.
“Zander was taken off for 10 minutes after what regarded like a standard deal with however there was a spike alert from the mouthguard.
“I do know in Tremendous Rugby there have been a few alerts and gamers had been saying, ‘there’s nothing flawed right here, I’ve simply made a deal with’, so we have got to look at that since you do not need to be taking our greatest gamers off the sphere for 10 minutes if there are not any points round concussion.
“We need to shield our gamers, that is for sure, however there is a bit extra work to do earlier than this know-how is right.”
Townsend was requested if he believed the know-how had been rushed in.
“It is a new factor within the Six Nations and it isn’t been used at membership stage previous to the Six Nations,” he responded. “I might hope they’d be taught from this incident and clearly George Turner went off for 10 minutes within the earlier recreation.
“[We need] to verify it is as near correct as doable. That is what we would like.
“We have now numerous eyes watching and gamers are actually excellent at saying, ‘I’ve had a head damage right here, I’ve to go off’.
“I feel we simply must do a bit extra work right here earlier than we transfer on.”
