Bryant Gumbel is currently hospitalized in NYC after some sort of “medical emergency” … TMZ has learned.

Sources with direct knowledge tell us, the former “Today” cohost was transported Monday, just after 9 PM, from his Manhattan apartment building.

We’re told first responders had Bryant on a gurney, as they left the building and took him to a nearby hospital where he remains as of Tuesday afternoon.

It’s unclear what happened to the 77-year-old broadcasting legend, but we know he is still getting treatment. We’ve reached out to his reps for comment … so far, no word back.

We spoke to a family member, who told us Bryant is “okay,” but wouldn’t reveal any further detail about his condition.

Bryant formerly served as cohost of NBC’s long-running morning show for 15 years — first with Jane Pauley and Katie Couric. He was also a sportscaster and host of HBO’s acclaimed investigative series “Real Sports with Bryant Gumbel”.

His older brother, Greg — who was also a broadcaster, primarily in sports — died last year at 78.
