ABC News says Juju Chang is headed to "Nightline."
She'll be replaced as "Good Morning America" news reader by Josh Elliott, who's currently co-anchoring ESPN's "SportsCenter."
Chang will serve at "Nightline" as a special correspondent and fill-in anchor, as well as taking part in a number of the 13 prime-time hours that "Nightline" is planning for this summer. In a lengthy career at ABC News, she has been "GMA" news reader for 15 months.
Elliott joined ESPN in 2004 as a panelist on various shows at that network. In 2008, he was named co-anchor of "SportsCenter" with Hannah Storm.
ABC said Wednesday the changes will take effect in the coming weeks,.
