Pees diagnosed with cancer in summer

All sorts of information is emerging about the New England Patriots and defensive coordinator Dean Pees parting ways.

ESPNBoston.com's Mike Reiss has posted his analysis on Pees' surprising departure after six years with the team.

Boston Globe reporter Albert Breer writes Pees has been dealing with a series of medical issues. Pees was diagnosed with prostate cancer over the summer and had surgery. A blood clot was found in his leg shortly thereafter. Pees was hospitalized with shortness of breath during the Patriots' loss to the Houston Texans in the regular-season finale.

Pees also has released a statement through the club:

"My contract with the New England Patriots will expire in a couple of weeks, and I have informed Mr. [Robert] Kraft and Coach [Bill] Belichick that I will not seek to renew it. I enjoyed my time in New England, but feel this is the right time to pursue other opportunities. I had the privilege of working with some great coaches and great players over the past six seasons and leave the Patriots with some wonderful memories that will last a lifetime. In addition to the players and coaching staff, I want to thank the Kraft family, the media and the fans for all of their support."
