Quarterback Sam Darnold opened his Seattle Seahawks tenure with a perfect first drive in Friday night’s preseason game against the Kansas City Chiefs. The former Jets and Panthers starter completed all four of his passes for 34 yards before running back Zach Charbonnet finished the 70-yard march with a one-yard touchdown run. Seattle, which entered the exhibition as a five-point favorite, used the quick score to establish early momentum. The game marks Darnold’s first live action since signing a one-year deal aimed at securing the Seahawks’ backup job behind starter Geno Smith. No further details on playing time or final score were immediately available.
