Romain Grosjean is concerned he could be hit with a race ban after notching up his 10th penalty point of the season at the U.S. Grand Prix.
Grosjean took out Charles Leclerc while racing for position on the first lap in Austin and was given with a three-place grid drop for this weekend's Mexican Grand Prix as well as a single penalty point on his superlicence. If he accrues two more penalty points in Sunday's race -- which would make 12 points over a rolling 12 month period -- he would be banned from the next race in Brazil and, having been banned from the Italian Grand Prix in 2012, he admits he is worried about his rising tally.
