After facing racial abuse at the Sydney Cricket Ground (SCG) during the third Test, India pacer Mohammed Siraj was reportedly labelled a "grub" by a group of fans at The Gabba on the opening day of the fourth Test against Australia on Friday. The Indian team had lodged an official complaint after the crowd at the SCG allegedly racially abused pacers Jasprit Bumrah and Siraj over the second and third days of the Sydney Test. In fact, Cricket Australia even started an investigation to get to the bottom of the issue.

According to a report in The Sydney Morning Herald, Siraj didn't spend much time in front of section 215 and 216 at the Gabba on Friday, but that's where a spectator – who asked to be identified only by the first name – said that the fast bowler was repeatedly called a "grub" by vocal spectators.

Siraj was not the only Indian player who faced the unruly behaviour of the crowd, debutant spinner Washington Sundar was also called "grub" by the spectators.

"The guys behind me have been calling – shouting – both Washington and Siraj grubs. It started targeted at Siraj and it was a chant similar to the SCG one (in which fans sang to the tune of Que Sera, Sera but substituted the lyrics with Que Shiraz, Shiraz)," the newspaper quoted a spectator named Kate as saying.

"But this time it was Siraj. I suspect it's not a coincidence that it's Siraj being targeted post the SCG stuff.

"At one point, a man in that section was heard yelling, 'Siraj, give us a wave, give us a wave, give us a wave. Siraj, you bloody grub.'"

None of the Indian players sent to field at the boundary registered a reaction to anything said by crowd members all day.

Aside from Siraj and Washington being called "grubs", the rest of the 12,998 fans in attendance appeared to be on close to their best behaviour.

At Stump's on the Day One, skipper Tim Paine (38*) and Cameron Green (28*) stood tall as Australia's score read 274/5.
