The New England Patriots are pretty well set along the defensive line, but head coach Mike Vrabel said Friday the team will kick the tires about signing recently released defensive tackle Christian Wilkins.

Christian Wilkins, who was released by the Las Vegas Raiders on Thursday, kissed a fellow player on the head and the teammate took offense to it, a source told ESPN's Adam Schefter.

According to reports, the Raiders believe Wilkins did not properly follow his rehab program, leading them to release him under the vested veteran designation.
