The Miami Dolphins will be without starting left guard Josh Sitton for the remainder of the season due to a torn rotator cuff in his left shoulder, Armando Salguero of the Miami Herald reports.

Sitton suffered the injury in the second half of the Dolphins’ season opener against the Tennessee Titans and will require surgery to fix the tear.

The Dolphins will replace Sitton in the starting lineup with Ted Larsen, who took almost all the practice work at left guard during training camp when Sitton sat out. Larsen started eight games at guard for the Dolphins last season.

Dolphins offensive coordinator Dowell Loggains admits that Sitton’s absence will be an issue for the team moving forward.

“Does it change things? Absolutely,” Loggains said Wednesday per Salguero. “If you didn’t have someone at any position, you look to (say), ‘How is this matchup going to affect us in the game?’”

Sitton, 32, was in his first season in Miami after signing a two-year, $18 million deal with the Dolphins this past offseason. He had spent the previous two years with the Chicago Bears, playing 26 out of a possible 32 games. He also spent eight successful years with the Green Bay Packers and was an integral part of their Super Bowl-winning team in 2010.

A four-time Pro Bowler, the Dolphins will miss Sitton’s strong run blocking. He helped the Dolphins rack up 120 rushing yards in Week 1 against the Titans. He was also the most experienced member of the Miami line and had already taken up a prominent role in mentoring young left tackle Laremy Tunsil.

The Dolphins' first test without Sitton will come against the New York Jets in Week 2.
