Close, a three-time Tony Award and Golden Globe winner who also won a pair of Screen Actors Guild Awards during her four-decade career, had been expected to be one of 40 actors presenting awards, according to The Hollywood Reporter. That list includes Nicole Kidman, Halle Berry, Antonio Banderas, Ariana DeBose, Harrison Ford, Jessica Chastain, Samuel L. Jackson, Janelle Monáe, Michael B. Jordan and Sigourney Weaver and John Cho.
It is unclear who might replace Close, the entertainment news website reported.
People attending the ceremony at the Dolby Theatre, including reporters, were required to test negative by the event producers but did not need proof of vaccination, according to Deadline.
Last year, Oscar nominee Lin-Manuel Miranda had to skip the ceremony after his wife tested positive for COVID-19, according to the AP.
