The Arizona Cardinals went back to work Thursday amid media reports that coach Bruce Arians has changed his mind and decided to start Ryan Lindley at quarterback Sunday in the regular-season finale at San Francisco.

Arians does not talk to reporters on Thursdays, and offensive coordinator Harold Goodwin was not forthcoming about the reported quarterback switch.

"I guess we'll see on Sunday," Goodwin said.

Arians had said that rookie Logan Thomas would get his first NFL start against the 49ers, but apparently didn't like what he saw in Wednesday's practice.

Lindley was working with the No. 1 unit in the brief portion of Thursday's practice that was open to reporters., which includes the Arizona Republic, first reported the quarterback switch.

Saints don't blame Ryan

Saints linebacker Curtis Lofton doesn't necessarily believe New Orleans' much-maligned defense needs wholesale changes heading into next season.

While some roster adjustments will have to be made following a 6-9 non-playoff campaign, Lofton thinks many pieces are already in place that will allow New Orleans to regain the form that took the Saints to an 11-5 record in 2013 and a spot in the NFC divisional playoffs.

One thing is clear, Lofton insists defensive coordinator Rob Ryan has to stay.

"I think Rob is one of the best defensive coordinators I've ever been around and played for," Lofton said. "Throughout the year, he stayed confident in himself and us.

"We let him down this year, so that's disappointing. He stayed the same old same old. We all love Rob and we'd run through a wall for Rob."

Kaepernick weighs options

Colin Kaepernick is in the process of considering how he might go about his offseason regimen to bounce back from a disappointing year, and employing a mechanics coach or quarterback guru as Tom Brady and other stars have done is being discussed.

"That's still in the works," Kaepernick said. "Just working on possibilities right now."
