Seahawks QB Sam Darnold ruled out with quad injury - ESPN

Seattle Seahawks quarterback Sam Darnold will miss Sunday's game against the Arizona Cardinals because of a quad injury, coach Mike Macdonald announced Wednesday.

Darnold sustained his injury at the end of Monday night's loss to the Chicago Bears.

Macdonald said Darnold would be week-to-week but will not be placed on injured reserve.

The plan is for Drew Lock to start Sunday's game with Jalen Milroe as his backup, Macdonald said.

Lock has missed the past two games because of an elbow injury. Macdonald said the Seahawks would get both quarterbacks ready to play.

«We have full confidence in those guys and will have a plan in place,» Macdonald said.

Darnold missed most of the first two games due to a glute injury suffered on the first series of the season opener against the New England Patriots. In his absence, Lock threw four touchdown passes and zero interceptions while posting the sixth-best Total QBR (82.5) over the first two weeks.

In a 31-7 win over Arizona in Week 2, he went 19 of 26 for 235 yards and three touchdowns.

Monday night's loss dropped the defending Super Bowl champion Seahawks to 4-4 this season.
