Cricket players in Australia could be wearing concussion sensors in their helmets as early as next summer.

Cricket Australia (CA) has revealed it is in the early stages of trailing state-of-the-art sensor technology to help understand the impact of head knocks.

"We've put a high priority on understanding concussion, like most other sporting organisations in the last three to four years are doing same thing, and sensors are one of those," Cricket Australia sports science and medicine manager Alex Kountouris said.

It is a move that is already being trialled in the NFL.

Sensors are placed inside a player's helmet and ranks the level of impact on hits to the helmet.

That ranking is relayed to a handheld device that is in the hands of coach or trainer, who can determine whether or not the player needs to undergo concussion testing.

"Once we understand the technology better and have confidence then we'll look to introduce it and trial it in games," Kountouris said.

"It won't happen this summer it's more likely to happen in the next 12 months."

Australia coach Darren Lehmann says he would happily support the introduction of the sensor technology.

"Anything that helps the safety of the players I'm all for," he said.

Concussion sub to be trialled this summer

Almost two years since the death of Phillip Hughes, New South Wales cricketer Daniel Hughes was subbed out of a one-day match with concussion.

CA is trailing a substitution rule for this season's Big Bash and domestic one-day games.

While CA is leading the charge, the International Cricket Council (ICC) is yet to change the guidelines that govern first-class matches.

That means there are no provisions for a concussed player to be replaced during Sheffield Shield or international fixtures.

"Cricket is a sport that doesn't have substitutes, so it is a massive cultural change and a big change for the game to allow that and we understand that," Kountouris said.

"We're realistic about the complexity of it. The game's been around for over 100 years and didn't have substitutes, so for us to get it in and trial it is a big thing."

CA will feed back the results from its substitution trial to the ICC body at the end of the summer.
