Arizona Cardinals defensive end J.J. Watt is retiring from the NFL following an illustrious 12-year career.

The three-time Defensive Player of the Year winner took to social media on Tuesday to announce his decision to retire at the end of the Cardinals’ regular season.

"Koa’s first ever NFL game," Watt said of his two-month-old son, Koa James Watt. "My last ever NFL home game."
