Seattle Seahawks quarterback Russell Wilson will play his former team in the Sept. 12 season opener at Lumen Field.

Pete Carroll favoured Alex Smith over Drew Lock after Seattle's 27-26 preseason loss to the Cowboys.

Carroll has claimed all along that Smith is ahead of Lock in comprehending Shane Waldron's offence.

Lock missed the second preseason game with COVID-19.

He had a beautiful touchdown pass but three interceptions versus Dallas, two of which weren't his fault.

When asked why he chose Smith, Carroll said the 10-year veteran kept earning the lead.

"We placed him up against the opposition, and Drew took his shots," Carroll said.

"Those guys got along well and encouraged one another.

Geno knows our things, he does it well, he understands it, and he's fantastic at football.

For Smith, it's another chance to be a QB1 despite early-career troubles and a sucker-punch-related broken jaw.

Smith joined Seattle in 2019, backed up Wilson for 3 seasons, and re-signed in April for $3.5 million.

He's 13-21 as a starter, including 12-18 with the New York Jets, who drafted him in 2013.

Lock emphasised that Smith and Lock will have each other's backs after Carroll's statement.

Last summer, Teddy Bridgewater beat Lock in Denver. Lock vowed to seize any opportunity.
