Haim's guitarist and lead singer, Danielle Haim, was in a car accident on Friday night (6 February) on her way to a pre-Grammys party.
A representative for the band told Billboard that the musician is "fine", though it did leave her unable to attend two events leading up to tonight's Grammys ceremony.
No other details of the accident have been released, and it's currently unclear whether the band, who are nominated in the Best New Artist category, will attend the awards.
As well as her skills in guitar and singing, Danielle is also a talented drummer, having joined The Killers onstage in San Francisco back in August.
Haim are currently working on their second album, the follow-up to 2013's critically and commercially successful Days Are Gone.
