Brock Purdy threw for 255 yards and three touchdowns, and the San Francisco 49ers never trailed in a 36-24 victory over the Seattle Seahawks on Thursday night.
Samuel had a 76-yard catch-and-run touchdown and finished with three catches for 102 yards for the defending NFC champions (3-3), who moved into a tie with Seattle (3-3) for first place in the NFC West after an uneven start to the season.
George Kittle added five receptions for 58 yards and two scores for the 49ers, who beat the Seahawks for a sixth straight time. Kyle Juszczyk had a late TD run, and he and Kittle both celebrated their scores by leaping into the stands to embrace their wives, who were sitting together in the first row.
