GREEN BAY, Wis. — Pass-rushing linebacker Clay Matthews will miss the Packers' game today against the Lions because of ankle and hamstring injuries.
Green Bay downgraded Matthews' status for the home opener from questionable to out after practice Saturday. Matthews has not practiced all week.
Matthews hasn't missed a game since he sat out the final two games of the 2013 season after he broke his thumb for the second time that season.
Green Bay also will be without Morgan Burnett (groin) after the starting safety was ruled out.
Two other key defensive players with knee injuries were downgraded from questionable to doubtful: defensive tackle Letroy Guion and defensive end/linebacker Datone Jones. Top cornerback Sam Shields (concussion) has already been ruled out.
KAEPERNICK PROTESTS WITH HIGH SCHOOL TEAM: Protests by high school teams during the national anthem have been in solidarity with 49ers quarterback Colin Kaepernick.
On Friday night, Kaepernick joined them, kneeling behind players and coaches from Castlemont in Oakland, Calif., as they took part in a "die-in" protest, laying on their backs with their hands up during the national anthem.
Kaepernick visited the school a week after the team kneeled and raised their firsts during the national anthem before last week's game.
Roger Putin? Former receiver Joe Horn has never been shy about his animosity toward commissioner Roger Goodell, but he has now taken it a step further.
"Roger Goodell is the Vladimir Putin of the NFL when it comes to players," Horn told SI.com. "Putin punks every country when he gets ready to. And there's no rules when it comes to Putin, and Goodell is the same …way when it comes to players. He sets all the standards."
Horn's 12-year playing career, mostly with the Saints, only overlapped briefly with Goodell's tenure. Paul Tagliabue was commissioner for most of Horn's career, including his famous cellphone celebration that resulted in a $30,000 fine from the league. But Horn has been a harsh critic of the league under Goodell's leadership, and he's one of the many former players who has sued the league over brain injuries.
FALCONS' JONES BACK: Julio Jones has joined practice for the first time this week, increasing his chances to play in the Falcons' game at New Orleans on Monday night. After being held out on Thursday and Friday with a calf injury, Jones was limited in Saturday's practice. Coach Dan Quinn said the All-Pro receiver is no longer is bothered by the ankle injury that slowed him before the calf injury. Rookie strong safety Keanu Neal is expected to make his debut against the Saints. Neal, a first-round pick from Florida, had preseason arthroscopic knee surgery and missed the first two games.
