A day after being traded to the Chicago Bears in a stunning deal, Khalil Mack said goodbye to Oakland Raiders fans.
The 2016 NFL Defensive Player of the Year had held out the entire preseason as he sought a new long-term deal with Oakland.
The Raiders dealt Mack and a second-round draft pick to the Bears for four draft picks, including two first-round selections.
"Raider Nation the love you’ve shown my family and I for the past 4 years has been amazing we loved every minute of it!" Mack tweeted on Sunday.
"Unfortunately it has come to an end but I will cherish my time in Oakland forever and will forever have love for the Nation!"
The Bears then made Mack the highest paid defensive player in history, signing him to a six-year, $141million deal.
Earlier on Sunday, Raiders coach Jon Gruden addressed the trade, telling reporters: "It wasn't my goal to trade Khalil when we got here. One of the reasons I'm here is because of him."
Gruden also noted that the team will "be second-guessed until the cows come home on this. I understand that".
