Clarke questions Smith's 'brain fade' excuse

Former skipper Michael Clarke has aired his concerns over the Australian's use of the DRS system, and questioned Steve Smith's 'brain fade' claims.

After Virat Kohli claimed Australia were systematically rorting the Decision Review System (DRS) in Bangalore, Clarke said he was keen to find out more about the explosive claims.

"I want to find out from the Australian team if they're using the DRS in that way, if they are then that is unacceptable," Clarke told TV station India Today.

"My concern and my worry is that when you look at the footage of what happened with Steve Smith, Peter Handscomb ... actually suggests to Steve Smith to turn around and have a look at the support staff.

"If it is only a one-off, I don't think that would have happened.

"The fact that Peter Handscomb is even thinking about telling the Australian captain to turn around and look to the support staff, I've got my concerns."

Earlier, Smith apologised for looking up to the dressing rooms for assistance with the DRS, calling it a "brain fade".

"It’s the first time it’s happened,” Smith said.

Handscomb later tweeted it was his fault that the skipper looked up to the dressing rooms.

Former India captains Sourav Ganguly and Sunil Gavaskar both called on the ICC to take action against Smith, but the talented batsman is expected to escape punishment.

Gavaskar noted the incident involving Smith and Handscomb was "quite blatant" and not "in the spirit of the game".

"We have to see what the ICC and match referee do ... the match referee and the umpires should look into it," Gavaskar told NDTV.

Ganguly, who had plenty of run-ins with Steve Waugh when the pair were leading their respective sides, declared "action must be taken".

"If the umpires themselves saw Smith infringing on DRS rules then they must report and take action. The umpires and match referee must ensure this doesn't happen in future," Ganguly told Aaj Tak.
