CHARLOTTE, N.C. -- Pro Bowl linebacker Thomas Davis will be suspended for the first four games of his final NFL season after testing positive for a banned performance-enhancing drug.
Davis, who already has said he will retire after the 2018 season, made the announcement Friday on social media, calling it "by far one of the saddest days of my NFL career.''
Davis, 35, also posted a video with the message.
This is by far one of the saddest days of my NFL career. I never thought that this would happen to me. I've worked extremely hard to do things the right way on and off the field.
