Renshaw was struck twice on the helmet, once while batting on day one and then again while fielding at short leg on day three, when he was taken from the field.
On the third day, Renshaw, fielding at short leg, was hit on the helmet from Sarfraz Ahmed's attempted sweep shot off Stephen O'Keefe.
He was hit in the grill by a sharp Mohammad Amir bouncer on the opening day's play.
After being cleared by Peter Brukner, the Australian team doctor, Renshaw continued batting and went on to compile a memorable century.
Peter Brukner, the Australian team doctor said,
Renshaw rested in the dressing room and then, when we returned to the hotel, we performed concussion tests and his cognitive, balance, co-ordination and reaction times were all within normal limits.However, on Friday morning he was still symptomatic and so we have taken the decision to withdraw him from the match as he is suffering from concussion.
Brukner also said that Matthew Wade, Australian wicketkeeper, would take his place on Day four after being forced off the field early on the third day with illness, forcing Peter Handsdcomb to take the gloves.
Australia will have to bat with 10 men in the team's second innings as there is currently no provision for a concussion substitute in a Test match.
