PHILADELPHIA (AP) – Packers linebacker Clay Matthews hurt his shoulder on Philadelphia’s first drive Monday night.

Matthews was injured when right tackle Allen Barbre leveled him down field. The six-time Pro Bowl pick went to the sideline to get examined and wasn’t on the field for the next drive.

The Packers already were missing starting linebackers Jake Ryan and Blake Martinez.
