Six new performers were named alongside Tanya Reynolds in Ted Lasso season 4's cast announcement.
Apple TV announced seven newcomers in total: Tanya Reynolds, Jude Mack, Faye Marsay, Rex Hayes, Aisling Sharkey, Abbie Hern, and Grant Feely. Since the question excludes Reynolds, six other performers remain.
This is a counting question about the announcement, not a count of every actor appearing in the season. The established returning cast was listed separately, and Jason Sudeikis was also treated separately as the show's star and executive producer.
The six additional newcomers were Mack, Marsay, Hayes, Sharkey, Hern, and Feely. Keeping the categories separate prevents the common mistake of answering seven, which is the full number of newly announced performers rather than the number alongside Reynolds.
