Mary Carillo, Ato Boldon and David Feherty will serve as NBC Olympics correspondents in PyeongChang, while Joshua Cooper Ramo returns as a contributor.
They join previously announced correspondents chef David Chang and 1984 Olympic champion figure skater Scott Hamilton.
Correspondents will explore the culture, people and traditions in South Korea, while also telling athlete and competition stories.
Carillo, a former WTA player and longtime tennis analyst, will cover her 14th Olympics and 11th with NBC Sports. She will continue to provide travelogues about the Olympic host city and country, as she has done since the 2008 Beijing Games.
