Detroit Lions head coach Dan Campbell was very excited in his postgame press conference after beating the Miami Dolphins. But he also had some discipline to announce.
Lions starting left guard Christian Mahogany didn’t play at all Sunday against the Miami Dolphins. Instead, backup interior offensive lineman Miles Frazier started at left guard.
CBS Sports’s Melanie Collins reported the lineup change early during the game’s broadcast Sunday. After the game, Campbell told reporters Mahogany was benched for disciplinary reasons.
“That was team rules. It was really that simple,” Campbell said on Mahogany’s benching. “Miles [Frazier] deserved his opportunity, so he got it.
“Doesn’t mean it stays that way. But that was the way it was going to be today.”
Mahogany started six of the team’s first seven games of the season. Before Sunday, the only game he missed was because of injury.
Lions Bench Christian Mahogany for Violating Team Rules
Campbell kept how Mahogany violated team rules private when speaking to reporters Sunday.
But this wasn’t an example of a “soft benching,” which has gained some popularity online with certain players losing starting job over recent weeks. Campbell was direct that Mahogany didn’t play in Week 9 because of a team violation.
The Lions head coach also wasn’t clear about how long the benching will last. But the open-ended way Campbell addressed that fact could mean Mahogany will return in Week 10 against the New England Patriots.
The Lions will face the AFC defending champions in Germany next Sunday.
Mahogany is a significant upgrade over Frazier. So from a football standpoint, it would be better for the team’s offense if the left guard’s benching ended earlier rather than later.
Mahogany has started 18 games in his NFL career. Last season, he started 11 contests. Before Sunday, the 26-year-old had started every game but Week 2 this campaign.
Detroit Football Network’s Justin Rogers reported Frazier told reporters he learned he was starting two days ago. Mahogany didn’t speak to reporters after Sunday’s game.
Miles Frazier Plays Left Guard in Sluggish Offensive Outing vs. Dolphins
While the Lions defeated the Dolphins in Week 9, they only scored 19 points. Detroit didn’t reach the end zone until late in the third quarter.
The Lions only had 270 yards, averaging 3.6 yards per carry and 5.8 yards per pass attempt against the Miami defense.
Detroit shouldn’t pin all those struggles on Mahogany’s absence. But that likely didn’t help. Pro Bowl running back Jahmyr Gibbs only posted 3.7 yards per carry; he’s a 5.2 yards per carry average runner in his career.
The Lions offensive line also allowed three sacks and seven quarterback hits against signal-caller Jared Goff.
Sunday was Frazier’s first career start. He played as a reserve lineman in 12 contests prior to Sunday.
This season, though, Frazier had only lined up for three offensive snaps before Week 9.
The Lions grabbed Frazier at No. 171 overall during the fifth round of the 2025 NFL Draft. Interestingly, Mahogany was a sixth-rounder the prior year.
In Week 2 when Christian Mahogany didn’t play, Ben Bartch started at left guard. The Lions placed Bartch on injured reserve during the team’s Week 6 bye.
