A piece of scaffolding, knocked loose by strong winds, struck Chenoweth, who fell to the ground. The actress, according to the New York Post, suffered a brief seizure following the accident and was later fitted with a neck brace and taken to Bellevue Hospital.
A witness told TMZ.com that when Chenoweth fell, she also hit her head on the pavement.
A spokesperson for the New York City Fire Department told the Associated Press that a woman had suffered minor injuries at the Brooklyn location, but he wouldn't identify the person.
Chenoweth is listed in stable condition, according to the Post.
CBS Entertainment announced on June 26 that Chenoweth ("Pushing Daisies"), who also won a Tony for You're a Good Man, Charlie Brown (and was nominated for playing Glinda in Wicked), will make her debut in the series with its fourth-season premiere in September.
