At PBS, a Change in the Lineup

Charlie Gibson, who now anchors the show solo, called the segment "hugs and handshakes and a little bit of humor."

"Many of you who watch this broadcast, and even many who don't, have been kind enough in recent weeks to inquire about the welfare of Bob Woodruff," Gibson told viewers.

"For the first time since his injuries, he came back to the newsroom today," Gibson said while viewers saw Woodruff in the office, surrounded by a mob of staffers:

On the tape, ABC News President David Westin hugged Woodruff: " So, the plan was not to mob you, right? This was beautifully executed."

Woodruff said he was unconscious for 36 days, Gibson explained to viewers:

Woodruff to staffers: "I woke up in this hospital and I looked up and I just thought about you guys and I thought about everything that I wanted badly to come back to."

Wearing a blue shirt and jeans, he looked thin, his dark hair cut extremely short, with a jagged scar running along his scalp and what appeared to be scarring on the left side of his face. He was accompanied by his wife, Lee.

Lee Woodruff to staffers: " Bob is the luckiest guy in the world, as his surgeons have said, but I also think a large part of healing is being surrounded by people who care about you and love you and he has had that from everyone here."

" He has had it for the past five months . . . And he's got it for the future," Gibson said, as viewers saw a shot of Woodruff walking down a hall, with Gibson right behind him.

Woodruff: "Ma n, it's good to be here."

Last week, Charlie Gibson's second as anchor of "World News Tonight," marked that show's lowest delivery of viewers -- 7.05 million -- since at least the start of People Meters in 1987. Gibson anchored Monday through Thursday; Terry Moran anchored on Friday.
