NBC newsman Tom Brokaw was hospitalized Thursday morning after appearing on the MSNBC show Morning Joe. 

The network said in a statement that Brokaw felt "light-headed" on the set of the program -- which originated from Charlotte, NC, where the Democratic National Convention is being held -- and was taken to the hospital "out of an abundance of caution." After undergoing tests at the hospital, Brokaw "was pronounced in great health" and discharged, the statement said.

The 72-year-old NBC News special correspondent took to Twitter to explain the incident. "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..." he tweeted. 

Brokaw -- who has served as special correspondent for NBC News since stepping down as anchor of Nightly News in 2004 -- has kept up a busy schedule of on-air appearances since last week's Republican National Convention.
