Watt jokingly tweeted that he was trying to "steal" ESPN insider Adam Schefter's "job for a day" before revealing the move.
"Trying new things in retirement, so let’s steal @AdamSchefter job for a day... TE Zach Ertz has requested & been granted his release from the Arizona Cardinals. The 3-Time Pro Bowler plans to sign with a contender and make a run at his 2nd Super Bowl ring," Watt wrote.
Schefter responded shortly after, confirming that the Cardinals and Ertz were "mutually parting ways."
Ertz, who suffered a season-ending knee injury last November, made seven starts for the Cardinals in 2023, recording 27 receptions for 187 yards and one touchdown. The 33-year-old signed a three-year, $31.65 million extension with the Cardinals during the 2022 offseason after being acquired by the franchise in a trade with the Philadelphia Eagles midway through the 2021 season.
Ertz was selected by Philadelphia at No. 35 overall in the second-round of the 2013 NFL Draft and was a three-time Pro Bowl selection, which included the 2017 season in which the Eagles won their first Super Bowl in franchise history.
