The Las Vegas Raiders made the surprising decision to part ways with defensive tackle Christian Wilkins last week, and void the remaining $35.2 million of guaranteed money on the four-year, $110 million contract he signed last offseason.

The Raiders' abrupt release of Christian Wilkins last week wasn't only about his lingering foot injury, it seems.

Though much of Wilkins' release was related to his foot injury, HR reportedly investigated last week after the DT kissed a teammate on the head.
