The Force India driver had to swerve around the slow-moving Mercedes W05 while on a flying lap just before turn 14. It looked as though Rosberg had attempted to move off-line as Perez turned in the same direction to avoid him.
The stewards decided to investigate the incident and confirmed after the session that the Australian Grand Prix race winner had escaped serious punishment, but had instead been given a reprimand.
They ruled that he “slowed unnecessarily and recklessly in front of car 11 [Perez] between turns 13 and 14″ during the floodlit practice two, which Rosberg finished second fastest in behind his team-mate Lewis Hamilton.
Meanwhile, no further action was taken against Esteban Gutierrez after the stewards investigated the Mexican driver for holding up Felipe Massa in the final sector during the second session.
They said: “After hearing from the driver and reviewing the video evidence the stewards decided that the incident was not an impeding situation.”
