ORCHARD PARK, N.Y. (AP) Buffalo Bills safety Aaron Williams has returned to practice after missing nearly a month recovering from a concussion and is set to start in the team's season opener at Baltimore on Sunday.
Coach Rex Ryan provided the update Tuesday, when the team resumed practicing following a three-day break. Williams has been out since Aug. 11, when he was hurt during a heavy collision with receiver Dez Lewis at training camp.
The Bills took extra precaution with Williams, who sustained a severe neck injury that limited him to playing just three games last season.
Right tackle Seantrel Henderson returned to practice after missing last week due to an undisclosed reason.
Starting running back LeSean McCoy was excused from practice for personal reasons.
