LAS VEGAS — Chase Garbers was 12 of 22 for 141 yards and the Las Vegas Raiders finished the preseason undefeated after Friday’s 23-6 victory over the New England Patriots.

It marked the first time in franchise history the Raiders (4-0) finished undefeated in the preseason.

Las Vegas scored on three of its first four possessions as a group of Raiders backups and hopefuls started the game by running roughshod through the Patriots’ first-team offense and defense.

Jarrett Stidham, who will back up quarterback Derek Carr in the regular season, was 4 of 6 for 72 yards, while running backs Zamir White and Brittain Brown each scored a touchdown for Las Vegas.

Raiders kicker Daniel Carlson was 3 for 3 on his field-goal attempts and finished the preseason 9 for 9.

New England quarterback Mac Jones and the Patriots’ starting offense played four possessions, two ending in a three-and-out, one with an interception, and the final one with a field goal.

Jones was 9 of 13 for 71 yards with one interception. Brian Hoyer finished 6 of 7 for 47 yards, and Bailey Zappe was 10 of 14 for 84 yards with an interception for the Patriots (1-2).

For the preseason, across seven series, the Patriots’ starting offense had four end without a first down, one end in a turnover, one with a touchdown and one with a field goal.

After stopping New England on its opening drive, the Raiders opened the scoring with a 23-yard field goal.

Then, five players after Luke Masterson picked off Jones, White ran left just inside the pylon to make it 10-0 with 3:20 left in the first quarter.

Las Vegas’ defense handled New England the rest of the way, holding the Patriots to two field goals over their final eight possessions.

LEARN NOT TO LOSE

At the start of training camp, Raiders Coach Josh McDaniels emphasized limiting mistakes, saying, “You can’t win until you learn how to not lose.”

The Raiders did not commit a turnover the entire preseason.
