The United States Grand Prix stewards have deemed no action was necessary following an incident involving Heikki Kovalainen and Timo Glock during the race.
The Finnish Caterham driver overtook his Marussia rival by making contact at Turn 15 when battling for 18th position near the end of the event.
After the race, the stewards labelled it as a racing incident and said no further action was needed.
Kovalainen finished in 18th, with Glock in 19th.
"Late in the race I was able to get past Heikki in Turn 12 but in Turn 15 he dived in again and retook position, pushing me off the track a bit," said Glock.
