ORCHARD PARK, N.Y. -- The Buffalo Bills have signed seven of their eight draft picks, including first-round selection Ed Oliver, while veteran quarterback Derek Anderson is retiring after 14 seasons.
The Bills announced the signings and Anderson informed the NFL of his retirement on Thursday, a day before opening their rookie minicamp.
Anderson's decision to retire comes as a surprise, after the 35-year-old signed a one-year contract a day after Buffalo closed its season. The Bills lured him out of semi-retirement in October to serve as an experienced backup to then-rookie Josh Allen.
