Former Patriots and Bills RB Damien Harris announced his retirement Monday. Harris signed with Buffalo last offseason but appeared in just six games before suffering a neck injury. Although not deemed season-ending at the time, it wound up sidelining him the rest of the year. We're guessing that injury also factored into his retirement (at age 27), though that hasn't been reported as of this writing. There's no fantasy impact here unless you have Harris on your dynasty roster. (Feel free to release.) The Bills sport only James Cook and Ty Johnson at RB on their current roster (plus Darrynton Evans on a Futures contract). We'd bet on at least one upcoming RB addition -- and quite possibly more.
