There's no word if she has the job full-time, but Savannah Guthrie is in Ann Curry's former chair as co-host of NBC's "Today" show.

Guthrie sat beside Matt Lauer on Friday, discussing stories about the Colorado wildfires and Supreme Court health care decision. She replaced Curry, who was cut loose Thursday after one year as Lauer's co-host.

NBC hasn't said anything publicly about who will replace Curry full-time. The show's introduction, which normally announces the show's hosts, omitted that feature on Friday.

The turnover comes as NBC's profitable morning show faces its most serious ratings challenge from ABC's "Good Morning America" since the mid-1990s.
