Clay Matthews

The Green Bay Packers should probably start looking at free agent linebackers. Clay Matthews broke his thumb in the win against the Detroit Lions on Sunday.

Add to that Brad Jones, who hurt his — what else? — hamstring and Robert Francois, who tore his Achilles tendon.

We should know more about Matthews’ injury today, but there’s a chance he’ll be able to play through it. If he doesn’t need surgery, Matthews could play with a cast. If he does need surgery, he’ll miss several games.

Matthews suffered the fracture in the third quarter when he sacked Matthew Stafford. Ironically, he was unblocked on the play and had a free shot at the quarterback.

Matthews sat out the fourth quarter Sunday. He also missed the second half of the Packers last game against Cincinnati because of a hamstring issue.

So when do we start calling this guy injury prone?

The good news is, both Nick Perry and Mike Neal stepped up on Sunday. Neal had a sack and Perry had two, in what was by far his finest game as a pro.
