F1's sporting regulations stipulate that a driver must not exceed a maximum time - set by the FIA - between the safety car line after the pit exit and the safety car line before the pit entry on their in-lap.

Both Williams driver Massa and Renault's Magnussen allegedly exceeded that limit and their teams have been summoned to see the stewards.

Massa qualified in 12th position, while Magnussen was knocked out in Q1 and finished in 18th.
