According to PCB, the duo met people from outside their bio-secure bubble and failed to maintain social distancing.
The 26-year-old played an unbeaten knock of 42 runs off 22 deliveries in first innings of the qualifier match.
The umpiring duo of Ahsan Raza and Rashid Riaz came under the scrutiny after they gave some wrong decisions in first half of Multan Sultans' innings.
This is not the first case of an international star being ruled out of the PSL owing to concussion.
While Multan have three wins from seven matches and are at the fifth place of the six-team table, Gladiators have just a solitary win to their credit so far in seven matches and form the base of the points tally.
While some people hailed Babar Azam for his heroic knock, the others praised the duo of Colin Munro (88* off 56) and Iftikhar Ahmed (71* off 39) for their match-winning partnership.
When the two sides met last earlier in this tournament, Kings won the match by 6 wickets.
All eyes will be on Gladiators' captain Sarfaraz Ahmed who will be desperate to keep his side in contention of play-offs race.
Multan Sultans resumed their tournament with a win against Karachi Kings. Meanwhile, Wahab Riaz’s men also earned their first win in the second phase of tournament on Saturday.
Wahab grabbed the catch in the third ball of the 8th over of the Lahore innings.
