ORCHARD PARK, N.Y. — Bills starting middle linebacker Paul Posluszny is expected to miss about six weeks after having surgery to repair a broken bone in his left arm.

Coach Dick Jauron said Wednesday that Posluszny’s surgery went well and that the team is hoping he’ll return “somewhere before the halfway point of the season.” Posluszny was hurt in the first half of the Bills’ season-opening 25-24 loss at New England on Monday.
Backup Marcus Buggs, who appeared in only four games as a rookie last year, is pegged to take over as starter on Sunday, when Buffalo hosts Tampa Bay.
Jauron said starting defensive end Chris Kelsay is listed day to day after hurting his knee against the Patriots.
