Three drivers facing grid penalties for F1's Malaysia return

So far, three Formula 1 drivers will have to serve grid penalties at this weekend's Bahrain Grand Prix in Malaysia.

Racing Bulls driver Arvid Lindblad will start at the back of the grid as his team fits new power unit components.

Racing Bulls announced on Thursday at Sepang that Lindblad would take multiple fresh power unit components that will trigger a back-of-the-grid penalty.

He's not the only driver facing a grid penalty this weekend, as Isack Hadjar revealed in his Thursday media session that he'd be facing a grid drop.

"It's going to be difficult for me, I should be taking five places penalty, but even like that, I believe it's a track [where if] you have the race pace, you go up," Hadjar said.

"If we can't, then that means we're not fast enough. So let’s see."

Franco Colapinto also has to serve a five-place drop for causing a collision with team-mate Pierre Gasly and McLaren's Lando Norris in Baku.

Colapinto was initially awarded a 10-second time penalty, but as he was out of the race and unable to serve the penalty, it was converted into a five-place grid drop for his next race.

Lindblad had a Turn 1 collision of his own as he ran into team-mate Liam Lawson, but the stewards quickly decided that no further action was required.
