For the next three to four games, the Green Bay Packers will be forced to replace their defense's best player with a combination of Mike Neal and Nick Perry.
ESPN's Adam Schefter reported Monday afternoon that the Packers are expected to be without linebacker Clay Matthews for the next month while he recovers from a thumb injury suffered during Sunday's 22-9 win over the Detroit Lions.
Matthews hurt the thumb when he landed awkwardly following a second-half sack of Matthew Stafford. He exited the game and didn't return.
Packers head coach Mike McCarthy told reporters earlier Monday that Matthews was visiting a specialist and that he was optimistic his star linebacker wouldn't be lost for the remainder of the season.
