ORCHARD PARK, N.Y. -- The Buffalo Bills are working out free-agent running back Karlos Williams and are expected to re-sign him, either to their active roster or practice squad, a source told ESPN NFL Insider Adam Schefter on Thursday.
Williams, whose workout was first reported by NewYorkUpstate.com, recently completed serving a four-game suspension as a free agent for violating the NFL's substance-abuse policy. The Bills released the second-year running back in August.
