The cast and crew of NFL RedZone had to evacuate their studio when an emergency alarm went off on Sunday.

During the broadcast, reporter Scott Hanson interrupted coverage of the Buffalo Bills and Philadelphia Eagles game to tell audiences of the "unprecedented" situation as the alarm could be heard in the background.

"Ladies and gentlemen, this is a first in my twenty-something year broadcasting career," he said. "We have an alarm going off in the studios of NFL RedZone right now, in our studios here in Inglewood, California. We are being told we need to evacuate the building. We do not know the nature of the emergency."

Hanson then went off air while the game played. He returned two to three minutes later telling audiences that he got clearance to stay on the broadcast. He signed off from a studio desk with the alarm still going off in the background.

Hanson posted on X, formerly Twitter, shortly after the broadcast ended to give an update that the scare was over.

"Well, that was…. interesting," he said. "Alarm has stopped. Apparently all clear. Still waiting on details. Thanks for watching NFL RedZone week 12 ! One to remember."

NFL Media later described the situation as "a false alarm."

"There was a false alarm at the NFL Network studio and thankfully there was no fire. No business functions, including NFL RedZone, were interrupted," NFL Media told Front Office Sports.
