Several sites reporting Hamilton has been summoned to see the Stewards allegedly leaving the track at T10 in Q3 and failing to slow for yellow flags in Q3?

Reputable sites are they? Don't see anything on the mainstream ones (ad it's very late after quali to be hearing about it). If he left the track at T10 that isn't a steward visit it's a lap deletion. Like Jody says, if he failed to slow for yellows he will get a 5 place grid drop.
