NBC News special correspondent Tom Brokaw, hospitalized on Thursday morning in "an abundance of caution," was discharged hours later, the network said.

Brokaw, 72, was taken to Carolinas Medical Center in Charlotte, N.C., after he said he felt "light-headed" on the set of MSNBC's "Morning Joe."

"After medical evaluation and a round of tests, Tom was pronounced in great health. … We're immensely grateful to the team at Carolinas Medical Center for their excellent care and professionalism," NBC News President Steve Capus said in a statement.

Brokaw tweeted at 10 a.m. that he was doing fine: "All is well. Early AM I mistakenly took a half dose of Ambien and made less sense than usual. Made a better comeback than Giants …"

Brokaw appeared on the show shortly after 7 a.m. and uttered a few sentences in which he recounted the story of former Treasury Secretary Bob Rubin stepping into a pool at a party on Wednesday night.

"There was a party at the top of the hotel yesterday that has a very sleek modern hotel. And their glass is not exactly clear in terms of where you walk through and where you step next. So Bob Rubin, former secretary of the Treasury, has a phalanx of people around him, he stepped [unclear] into the party room and deeply into the pool," he said.

Brokaw left the "Morning Joe" set afte r those comments.

The rest of the panel - which included hosts Joe Scarborough and Mika Brzezinski, MSNBC's Lawrence O'Donnell, political analyst Richard Wolffe and BBC America's Katty Kay - continued talking over video and images of President Clinton's Democratic National Convention speech on Wednesday night, without Brokaw's participation. When the cameras returned to the set about five minutes later, Brokaw was gone.

Brokaw served as anchor and managing editor of NBC Nightly News for 21 years. He has received the Edward R. Murrow Lifetime Achievement Award, the Emmy Award for Lifetime Achievement and was inducted as a fellow into the American Academy of Arts and Sciences.

He contributed to NBC's coverage of the 2012 Republican National Convention, as well as the Democratic National Convention.

Brokaw has participated in NBC's presidential election coverage every cycle since 1968 and has interviewed every president since Lyndon B. Johnson.
