The Packers enter a bye week at just the right time.

Coach Mike McCarthy just told reporters that outside linebacker Clay Matthews could miss “a couple weeks,” with his hamstring strain, while Nick Perry is getting a second opinion on his knee.

Matthews has a history of hamstring problems, but will in fact have a couple weeks before the Packers play again. They return Nov. 18 against the Lions.

Perry hasn’t played since injuring his knee Oct. 14 against the Texans, and if he and Matthews are both out, the Packers would be dangerously thin in terms of pass rush.

McCarthy also said they’re “still gathering information” about the hip injury of right tackle Bryan Bulaga, and that he was seeing a specialist. That doesn’t sound good.

There was good news, as wide receiver Jordy Nelson’s ankle injury wasn’t deemed serious.
