If the 49ers were last year's 49ers in the red zone and not this year's 49ers in the red zone, the Seahawks might have already been run over. Instead, Seattle hangs on with one half to go.

The 49ers lead the Seahawks 16-3 at halftime on Thursday Night Football.

San Francisco turned Seattle's two turnovers into just six points, and the 49ers went 0-2 in the red zone. The 49ers entered Week 6 ranked 30th in the red zone and scored just nine touchdowns on 22 possessions inside the opponent's 20-yard line. That cost them Sunday's loss to the Cardinals, when they scored a touchdown on six possessions in the red zone.

Matthew Wright kicked field goals on drives that ended at the Seattle 7 and 17. He scored another field goal on a drive that ended at the Seattle 23.

The game's only touchdown came on a 76-yard catch-and-run by Deebo Samuel following a pass from Brock Purdy. The 49ers struck out just once and gained 244 yards.

Purdy completed 9 of 14 passes for 139 yards, Samuel caught two for 87 yards.

The Seahawks had two drives deep into San Francisco territory. Geno Smith threw a pick to Malik Mustapha at the 49ers' 2-yard line after Seattle reached the San Francisco 25, and on the final offensive snap of the half, DK Metcalf's right toe landed on the end line in the end zone. The Seahawks, lined up at San Francisco's 2-yard line, had to settle for Jason Myers' 20-yard field goal on the final play of the half.

Seattle has just 133 yards rushing, with Smith going 9 of 18 for 109 yards. Metcalf had one catch for 30 yards and Jaxon Smith-Njigba had three for 47.

The Seahawks' other turnover came on Laviska Shenault Jr.'s fumble on a kickoff return after Samuel's touchdown.

The 49ers lost running backs Jordan Mason (left shoulder) and Mustapha (ankle) in the first half, although both are questionable to return. Rookie Isaac Guerendo replaced Mason and George Odum came on for Mustapha.

The 49ers get the kickoff for the second half.
