Formula 1 could say goodbye to Friday practices in the future, or drop to just one session; according to Ross Brawn.

Liberty Media are looking at various ways to shake up grands prix weekends, bringing both fans back to the circuits and increasing TV viewership numbers.

Brawn, F1’s sporting boss, has looked at the format of the race weekends and while he feels that qualifying and the grands prix are perfect as they are, he says they could change the Friday practices.

“I think the length of a grand prix is about right. It’s not too long, it’s not too short, it engages you,” Brawn told Sky Sports.
