Mathieu, Clark both out in season opener against Browns

The Kansas City Chiefs have released their list of inactive players for Sunday’s season opener against the Cleveland Browns at Arrowhead Stadium. Safety Tyrann Mathieu and defensive end Frank Clark will not dress for the game — but defensive tackle Derrick Nnadi will play.

Mathieu (illness), Clark (hamstring) and Nnadi (hip) had all been listed as questionable for Sunday’s matchup. Mathieu didn’t appear on Kansas City’s Friday’s injury report because he was still on the team’s Reserve/COVID list — but after his activation on Saturday, he was listed on an updated report.

On Saturday, the Chiefs also elevated practice-squad defensive back Zayne Anderson to the roster — and he is active for the game. As an elevated player, he will automatically be returned to the practice squad on Monday.

As he continues to recover from sports hernia surgery, backup center Austin Blythe (abdomen) had already been listed as out for the game.

The rest of the Kansas City inactives — cornerback Deandre Baker, guard Laurent Duvernay-Tardif and wide receiver Daurice Fountain — should be considered as healthy scratches.

All four of the team’s tight ends — Travis Kelce, Blake Bell, Noah Gray and Jody Fortson — are active for the game.

The Browns have also released their inactives. Wide receiver Odell Beckham Jr. will not play against Kansas City. Defensive end Jadaveon Clowney, center J.C. Tretter and safety Rodney Harrison Jr. will all play.

Beckham (knee), Clowney (illness), Harrison (ankle), Tretter (knee) and safety Grant Delpit (hamstring) had all been listed as questionable for Sunday’s matchup. Linebacker Tony Fields II and guard Michael Dunn had already been listed as out in Friday’s injury report.

On Saturday, the Browns elevated two of their practice-squad players: linebacker Elijah Lee and kicker Chris Naggar. Lee is active for the game, but Naggar will not dress.
