Rob Ryan fired

RanchReport.com has learned defensive coordinator Rob Ryan has been fired by the Cowboys.

Ryan had one year left on his current three-year deal.

Dallas, which was eliminated from playoff contention during the final week of the regular season, finished 19th in the NFL in total defense this year.

Cowboys owner/general manager Jerry Jones had hinted in previous weeks "changes" would be coming.

Thus far, this is the first ax to drop.
