Reports suggest that PCB's defence strategy against the charges of ball tampering and bringing the game in disrepute in the ICC hearing will be based on the initial disagreement between the umpires.
The on-field umpires changed the ball in the 56th over of England's second innings on the fourth afternoon. Hair then awarded England five penalty runs, indicating the ball had been tampered with.
As per the reports, Doctrove was initially of the opinion that the umpires allow play to carry on for a few more overs to help identify the cause of the change in the ball's condition.
Eventually, though, Hair is thought to have reasoned that if both umpires were in agreement that the condition of the ball had been altered then they should change it immediately. Doctrove then agreed and the ball was duly replaced.
