Quarterback Sam Darnold will miss the Seattle Seahawks' Week 9 matchup against the Arizona Cardinals due to a quad injury, as confirmed by coach Mike Macdonald. In Darnold's absence, Drew Lock will make his second start of the season.

Lock is also managing an elbow injury, which the coaching staff will monitor throughout the week. Seattle has Jalen Milroe ready as Lock's backup. Macdonald stated, "He's able to throw. How much, we're working through that right now," regarding Lock's condition.

The Seahawks are looking to bounce back after suffering a 34-17 loss to the Chicago Bears on Monday night. In that game, Darnold completed 17 of 34 pass attempts for 188 yards, two touchdowns, and one interception.

Lock previously started earlier this season when Darnold was sidelined due to a soft-tissue injury sustained during the Week 1 victory against the New England Patriots. Interestingly, that start was also against the Cardinals in Arizona, where Lock excelled, completing 19 of 26 passes for 235 yards and three touchdowns in a commanding 31-7 victory.

Seahawks QB comparison this season:

• Sam Darnold: 17/34, 188 yards, 2 TDs, 1 INT (Week 8)
• Drew Lock: 19/26, 235 yards, 3 TDs (Week 1)

The Seahawks will look to Lock to lead them to a much-needed victory against their division rivals.
