Mike Evans catches 2-yard TD after Sam Darnold's INT

It was a rough start for Seahawks quarterback Sam Darnold.

Darnold was sacked for a 7-yard loss by linebacker Jaden Dugger on second down and was intercepted by Renardo Green on third down on a pass intended for Jaxon Smith-Njigba.

The 49ers needed only four plays to go 18 yards to the end zone.

Mike Evans caught a 13-yard pass to the Seattle 2 and scored on the next play.

It is his third touchdown of the season.

49ers quarterback Brock Purdy is 2-of-5 for 15 yards and a touchdown after going three-and-out with two incompletions on the first possession.
