Both Charles Leclerc and Carlos Sainz are at risk of penalties at the Canadian Grand Prix, with both drivers called to the stewards following Saturday's qualifying.
Leclerc failed to go the right way around a bollard after going off-track.
Although the infringement has been dealt with leniently so far over the weekend, stewards have said punishments will be harsher in qualifying and the race.
More likely to be punished is Sainz, who blocked Alexander Albon on a flying lap in Q1. Although Albon made it into Q2, it is an infringement frowned upon by the FIA, with a three-place penalty the standard punishment.
