The Cam Newton era for the New England Patriots arrived on the ground.

Newton looked just fine as Tom Brady's replacement, rushing for two touchdowns Sunday, and the Patriots beat the Miami Dolphins 21-11 to open the season.

Newton rushed for 15 times for 75 yards and threw for 155 yards, leading a Patriots offensive attack that did most of its damage via the rushing game in their first game since the departure of Brady to Tampa Bay as a free agent.

“It was relatively picking up right where I remember the game to be," said Newton, played for the first time in more than a year. "I think it was just a feeling-through process as well with (offensive coordinator) Josh (McDaniels), coach Bill (Belichick), as well as (quarterbacks coach) Jedd (Fisch) to understand what they have. ... We made the adjustments and we executed.”

Newton's 75 yards were the most by a Patriots quarterback since Steve Grogan had 81 in 1977.

Sony Michel added a touchdown for New England, which had 217 of its 357 yards on the ground. Newton was 15 of 19 passing.

Newton said not even a postgame scrum in which a Dolphins player “got under my skin” by grabbing his chain could ruin the day.

“It’s football," Newton said. "For me no matter who it is, I play with a competitive edge and I respect the other team to have a competitive edge as well.”

Most of the sights and sounds normally associated with Gillette Stadium’s usually raucous crowd were silenced by a Massachusetts COVID-19 ordinance prohibiting fans from attending for at least the first two games of the season.

Aside from the play on the field, the only familiar staples of a normal game day were the presence of Patriots mascot and cheerleaders, though they cheered from a concourse high above New England’s entrance tunnel.

It didn’t seem to bother the Patriots, who had plenty to cheer about.

Miami struggled for most of the game offensively and lost top receiver DeVante Parker, who left in the third quarter with a hamstring injury.

Ryan Fitzpatrick was 20 of 30 for 191 yards and three interceptions. Miami was held to 269 total yards.

“I felt up front we played well," Fitzpatrick said. "I have to play better in my part.”

Newton scored from 11 yards early in the third quarter to put New England up 14-3. Late in the period, Jerome Baker kept the Dolphins in the game, stripping N’Keal Harry inside the 5-yard line, causing a fumble through the end zone for a touchback.

Miami then cut New England’s lead to 14-11 in the fourth quarter on a 1-yard TD run by Jordan Howard and 2-point conversion run by Fitzpatrick with 10:31 left.

The Patriots went quickly on their ensuing series and moved inside Miami’s 40, thanks to a 23-yard run by Julian Edelman and 15-yard penalty on Baker for a late hit. Newton muscled inside the 1 on a fourth-and-1 draw play. Michel went over the top for a TD on the next play.

The Patriots' defense then shut the door when Fitzpatrick was intercepted in the end zone by J.C. Jackson. Fitzpatrick was intercepted twice, once by reigning Defensive Player of the Year Stephon Gilmore.

“Just too many turnovers at the end of the day,” coach Brian Flores said.

Newton’s arrival was expected to bring more of a running mentality to New England’s offense and it showed early.

Newton carried on the second play of the game and capped an 11-play, 80-yard drive with a 4-yard touchdown run on the Patriots’ third possession to put them up 7-0. The 2015 league MVP was untouched as he crossed into the end zone on the play, spiking the ball and flexing as he was surrounded by teammates.

“He’s earned everybody’s respect,” Belichick said. "That’s all you can ask for anyone and he’s done that.”

PREGAME PROTEST

As promised in a video released by the team on Friday, the Dolphins exited the field prior to the pregame playing of “Lift Every Voice and Sing” about a half-hour before kickoff. Miami remained in the locker room during the national anthem, following through on a pledge the team made in its video.

Patriots players and staff, including team owner Robert Kraft, lined up in the end zone and stood together as a video rendition of the song by Alicia Keys played on the stadium video board as part of a league-wide nod to the social justice movement taking place across the country. The Patriots stood together on the sideline during the national anthem, many with their hands over their hearts.

MOVING ON UP

Edelman pulled in 6-yard pass early in the second quarter, his 600th career reception. He is now second in franchise history behind only Wes Welker (672).
