Buffalo Bills starting inside linebacker Paul Posluszny left Sunday's loss to Miami early in the third quarter with a right knee injury. Sal Maiorana of the Democrat and Chronicle spoke with Bills GM Buddy Nix on Monday, and Nix informed him that Posluszny's test results were encouraging.
Maiorana reports via Twitter that Posluszny is "probably out 2-3 weeks."
Posluszny played the entire first half against Miami, making eight tackles and a sack. He was injured on the first play of the third quarter when he made a rough landing out of bounds after tackling Dolphins running back Ronnie Brown on a two-yard gain. Posluszny sat on the sidelines while trainers examined his knee, then was seen standing and jumping on the sidelines before running - literally - into the locker room.
Keith Ellison replaced Posluszny in the lineup, recording six tackles in the second half. It's unclear if Ellison will continue to start this week, or if the Bills will use one of two veteran linebackers - Reggie Torbor or Akin Ayodele - inside next to starter Andra Davis.
Buffalo plays Green Bay, New England and the New York Jets over the next three weeks.
