Former Pakistan pacer Shoaib Akhtar on Sunday took to Twitter to criticise England speedster Jofra Archer, whose bouncer hit Australia’s Steve Smith on Day four of the second Ashes Test at the Lord’s Cricket Ground in London on Saturday.

Smith, who was then batting on 80, was hit on the neck by a searing Archer bouncer. The well-set batsman took off his helmet was laying on the ground looking in considerable pain.

Few England fielders and non-striker Pat Cummins rushed forward to attend him before Australia doctor convinced Smith to go off the field as a precautionary measure. Smith returned to bat later on and was eventually dismissed on 92.

Akhtar said it was not nice of Archer “to just walk away while Smith was in pain”.

“Bouncers are a part & parcel of the game but whenever a bowler hits a batsman on the head and he falls, courtesy requires that the bowler must go & check on him. It was not nice of Archer to just walk away while Smith was in pain. I was always the first one to run to the batsman,” tweeted Akhtar.

On Sunday, Smith was ruled out of the remainder of the Lord’s Test and remains in doubt for the third England-Australia Test, which will be played at Leeds.

“Smith passed a series of concussion tests after the incident and resumed his innings, but woke this morning with a “bit of a headache and a feeling of grogginess”, added the report.
