Packers linebacker Clay Matthews said a cheap shot he suffered Monday night is to blame for a separated AC joint in his left shoulder.
Matthews was hit by Eagles lineman Allen Barbre, a former Packer, on the Eagles' opening series. It was a de-cleating, but a legal, crack-back block by the Eagles tackle as Matthews was knocked on his backside.

"I wasn't a fan of it," Matthews said of Barbre's block Wednesday, via ESPN.com. "I mean, I've got a lot more to say about it, but I'm going to say it behind closed doors. It was cheap shot, but it is what it is. I ate it.
"Unfortunately I landed on my shoulder, and that's kind of what I've been dealing with since."
Matthews was clearly favoring his left shoulder on the final play of the drive that ended with Eagles quarterback Carson Wentz running into the end zone from a yard out.
Matthews, who briefly left the game due to the injury, is questionable for Sunday's matchup with the Houston Texans.
"I'm in some pain, no doubt about it," Matthews said. "There's some swelling [and] bruising, but we got an X-ray and nothing's broken so that's good. So we'll see moving forward the progress I make going into this game. That's ultimately the goal, but we've got some work to."
