Las Vegas Raiders coach Pete Carroll refused to comment on the reported human resources complaint that led to the team releasing $110 million defensive tackle Christian Wilkins.

Christian Wilkins’ NFL free agency just got even messier—and the full story may be far more complicated than anyone originally believed. The former Clemson Tiger and 2018 national champion was officially released by the Las Vegas Raiders on July 24,

“This franchise has a Commitment to Excellence on and off the field,” the Raiders said in a statement after Wilkins’ release. “With no clear path or plan for future return to play from Christian, this transaction is necessary for the entire organization to move forward and prepare for the new season.”
