More details emerged of Christian Wilkins' Raiders release, as a reported HR complaint came over an unwanted forehead kiss on a teammate by the veteran defensive lineman.

The Raiders voided the remaining $35.2 million guaranteed on Wilkins's contract, abruptly releasing him one year into his four-year deal that he signed with the team last offseason. ESPN's Adam Schefter reported at the time that the Raiders chose to part ways with Wilkins due to how he handled his rehab from a serious foot injury last year.

Former Raiders DT Christian Wilkins "playfully went to kiss a teammate on the top of his head," per ESPN's sources
