Unnamed sources informed to Celebrity news website TMZ that Chopra had slipped and fallen during a stunt and suffered a concussion after hitting her head.
ABC did not confirm this but said in a statement that a "minor incident" took place on the New York set of the FBI drama series on Thursday night.
The network added, "It would be premature to comment further until we have all the information. Although Priyanka was examined by a doctor, released and is home resting comfortably."
Chopra’s representative said she will return to work after the weekend. Walt Disney Co.´s ABC did not comment further on whether production of the show will be halted, but trade publication Variety said production will not be shut down while Chopra recovers.
The actress made her transition from Bollywood to Hollywood as the lead of "Quantico," in which she plays an FBI recruit turned CIA agent.
