The Twitter account of the National Football League was hacked Tuesday with a false message saying that Commissioner Roger Goodell had died.
The NFL quickly responded by saying the account had been hacked and Goodell was "alive and well." Goodell tweeted later in the day, making light of the matter.
This is the latest in a series of high-profile social media accounts being targeted by hackers. The Twitter account of singer Lana Del Rey was also hacked Tuesday.
Twitter declined to comment, directing CNBC to the NFL. The NFL said that it has "engaged law enforcement to look into the matter." It added that it is "reviewing and strengthening [its] cyber-security measures."
The tweets posted by the hacker were promptly deleted, but screen captures of the tweets can be seen below.
