Green Bay, WI (Sports Network) - Green Bay Packers All-Pro linebacker Clay Matthews could miss a couple of weeks with a hamstring injury, according to head coach Mike McCarthy.
Matthews left in the third quarter of Sunday's win over the Arizona Cardinals. He was able to limp to the sideline and eventually into the locker room, but was unable to return.
"Early diagnosis is it may be a couple of weeks," McCarthy. "Clay doesn't feel it's as bad as it was in the past."
Matthews joins a long list of Packers looking to benefit from the team's upcoming bye week.
Wide receiver Jordy Nelson, who sat out in Week 8 with a hamstring injury, suffered a sprained ankle on Sunday.
"I think he's going to be OK," McCarthy said of his team's leading receiver.
Right tackle Brian Bulaga also exited on Sunday with a hip injury.
Green Bay is also dealing with injuries to key players such as wide receiver Greg Jennings (groin), safety Charles Woodson (collarbone) and cornerback Sam Shields (ankle), all of whom were inactive in Week 9.
