Quoting the AP:

“Former ‘NBC Nightly News’ anchor Tom Brokaw said Monday that he had spoken with Woodruff’s wife, Lee, and said the family told him they had received ‘some encouraging news.’

‘The doctors had told them once they arrived that the brain swelling had gone down. In Bob’s case, that had been a big concern. Yesterday they had to operate and remove part of the skull cap to relieve some of the swelling,” Brokaw said on NBC’s ‘Today’ show.

The family also learned some details about the explosion from people who were there, Brokaw said.

‘Immediately after the explosion he turned to his producer and said ‘Am I alive?’ and ‘Don’t tell Lee,’ and then he began to cry out in excruciating pain,’ Brokaw said.

He said the family told him doctors don’t know for sure whether shrapnel penetrated Woodruff’s brain but they were removing additional shrapnel from his neck area.”
