In training camp, Bruce Arians had said if Jared Veldheer ever got hurt, D.J. Humphries would move from right tackle to the left side. That didn't happen when Veldheer went down for real -- John Wetzel moved into the lineup. But perhaps that could change now.

Thursday, offensive coordinator Harold Goodwin did not rule out the possibility of Humphries moving to the left side now. Both starting guards -- Mike Iupati (knee) and Earl Watford (shoulder) have been limited in practice. Wetzel can play guard, and the Cards also have Ulrick John, a right tackle whom they acquired earlier this season.

As far as Humphries moving, "we'll see," Goodwin said. "Maybe. Maybe not. We'll see. He's an athletic guy. He had some flubs last week in the red zone, especially on third down. But he's getting smarter. I don't know what we're going to do. We will see on Sunday."

The Cards have a lot of younger offensive linemen in play now. Goodwin's approach? "Try and keep the curse words to a minimum and be positive at all times."

As for what linemen will start against the Falcons, Goodwin was mum.

"We just have to have five guys out there, and I've got to do the best I can do coach them up," Goodwin said.
