Yuki Tsunoda was eliminated from qualifying just minutes after the Q1 session began. The AlphaTauri driver brought out the red flags as he crashed his AT02 at the Variante Alta chicane, spinning off backwards into the barriers.
The team are yet to confirm the extent of the damage to the car, or whether he'll take a penalty for a change of gearbox or chassis if required, but Tsunoda will be starting from the back regardless.
The rookie clambered from his car uninjured, and spoke to media afterwards where he apologised for his error and explained what he'd done wrong.
"Just pushing too much on entry," Tsunoda told Sky Sports F1.
"To be honest, until then, the lap felt great actually. Actually, I think potential was easy to go through Q1 with one tyre.
"I was too excited. For me, a series of mistakes and I feel really sorry for the team. You have to reset from today and just drive my best tomorrow."
Asked about the extent of the damage after the crash, Tsunoda explained he'd yet to chat to the team.
"For me, at the moment, I don't have anything for me. Anything like pain, I feel more to the car than me. Looks pretty bad actually on the back so I really hope the car can be repaired properly for tomorrow. But yeah, just feel sorry for the team today."
