Carlos Sainz and Sergio Perez have been summoned to see the stewards after the Ferrari driver was given a five-second time penalty for an unsafe release during the race.
Sainz was released into the path of Alonso after the pair pitted during the late Safety Car, which caused a lot of frantic activity in the pit lane as drivers switched tyres with 20 laps to go.
The stewards initially gave the Ferrari driver an in-race penalty, but they have now both been called up with regards to: "Alleged breach of Article 34.14 of the FIA Formula One Sporting Regulations – Pit Lane incident at 15:21."
Perez has also been summoned for a separate unsafe release incident.
