Goff will get reassessed throughout the week -- as the Lions prepare for a road game against the Cleveland Browns on Sunday -- before a decision is made, but as of Wednesday afternoon, backup signal-caller Tim Boyle was expected to take first-team reps in practice despite remaining on the injured reserve list after undergoing thumb surgery.
"If Jared can go, he'll go," Campbell said.
Goff's routine this week is expected to consist of a lot of rest to help the injury heal. He plans to test his strength to see if he can throw the ball as hard as he'd like without the injured oblique pulling. Goff said that if he's not able to compete, he'll be the best leader he can be to support his teammates.
"If I were to play, it would be a full go, there would be no limitations," Goff said Wednesday. "Last week, I don't know if the game plan was adjusted based on the weather or based on my injury, that's a better question for Dan probably, but there was definitely some limitations there that I don't know if I realized in the moment."
Goff suffered the injury during Detroit's 16-16 overtime tie with the Pittsburgh Steelers at Heinz Field on Sunday. He completed 14 of 25 passes for 114 yards with the injury nagging him throughout the game.
"If I couldn't have thrown, I wouldn't have gone. It was -- it was -- I don't want to sit up here and say I was hurt and whatever, make excuses," Goff said after the Pittsburgh tie. "But it was bothering me, but I felt I could compete and throw fine. And I felt like I did."
Goff has a NFL-worst 27.3 Total QBR this season.
However, Campbell still sees him as QB1 in the Lions' offense, with Boyle and David Blough on the roster as his backups.
"It's hard to say that he shouldn't be the guy right now," Campbell said Monday of why Goff deserves to be the starting quarterback. "It's hard to say that because -- there again, every time we try to throw it in dropback just about, our protection breaks down.
"Until we can do things right around him -- now, he -- yeah, there are throws we want to see that he needs to make," Campbell added. "There was a dart that we threw to Lif (Kalif Raymond) that he should make and he's pissed off about it, too. But ultimately, I still think, right now, he's the guy that gives us the best chance."
