Matthews is expected to miss a month due to a broken thumb sustained Sunday against the Detroit Lions, according to ESPN. Matthews got hurt while sacking Lions quarterback Matthew Stafford in the third quarter.
Packers coach Mike McCarthy said during a Monday news conference that Matthews has a doctor's appointment and he had nothing to announce yet on his status going forward.
"I'm hopeful it's not season-ending," McCarthy said. "Have to get all the opinions. There are a lot of little bones in there. You just don't know. The first step is to figure out what needs to be done. Then, you go from there. We've had players play with clubs, but the injuries are all different."
Matthews, 27, is a disruptive four-time Pro Bowl pass rusher who has 18 tackles, three sacks and two forced fumbles this season. For his career, Matthews has 222 tackles, 45.5 sacks, four interceptions and nine forced fumbles.
