Detroit — The Detroit Lions had another new combination of offensive linemen on the field Thursday night, as Trystan Colon subbed in at left guard for Kayode Awosika, who was ruled out with a foot injury earlier in the day.

But they fiddled with the combination a few more times throughout the night, intermittently inserting rookie Miles Frazier at left guard for his NFL debut.

“We just wanted to get a look at him, and really, it was just to get him introduced to the NFL, and trying to be smart,” Lions coach Dan Campbell said. “You still want to move the ball, but yet try to set him up to where he can have success.”

Frazier was flagged for two false starts, including one on a screen pass to Jameson Williams that looked like it was going for a big gain, but earned enough trust from the coaching staff to play more than Campbell originally intended.

Asked where he thought he did well in his NFL debut, Frazier said: “I’m just focusing on the bad right now,” but added that holding his own against a very talented Cowboys defensive interior “was an experience.”

“I have a lot of work to do,” Frazier said. “I’m not gonna lie. Me, I’m my biggest critic, so … I’m gonna get it fixed.”

Frazier wound up with 26 snaps, just 10 fewer than Colon’s 36. Frazier was dinged for allowing one hit on quarterback Jared Goff, two hurries and three pressures. Colon allowed three hits, one hurry and four pressures. Many of the plays where Goff had all day to throw came with Frazier on the field.

“He earned the right to keep going. He did good enough to where, ‘Alright, let’s give him another series,'” Campbell said. “Because really, we didn’t have intentions of giving him as much as he did, but we just wanted to kind of introduce him. And he did some good things, it felt like.”

Frazier was a fifth-round pick out of LSU this past spring. He might’ve competed for one of the starting guard jobs during camp, had a knee injury during the spring not sidelined him for most of his rookie season. But with Christian Mahogany and Kayode Awosika both injured, and Colon being the current weak link on Detroit’s offensive line, it would behoove the Lions if Frazier found his groove sooner rather than later.

It’s probably a bit unrealistic to expect Frazier to be a plus-player in the next few games, but the fact Detroit felt confident enough to put him out there speaks volumes. If he can just be serviceable, it would go a long way toward opening the playbook for Detroit’s offense.
