When the Dolphins’ secondary lines up Sunday afternoon against the Arizona Cardinals, the group will face its biggest test since the first week of the season.

Matching up against Houston’s Andre Johnson didn’t go as well as Miami had wanted. The Dolphins hope to do better against Larry Fitzgerald.

Fitzgerald, 29, is 204 yards away from eclipsing the 10,000-yard mark for his career. Now in his ninth season, Fitzgerald — along with the likes of Johnson and Detroit’s Calvin Johnson — is considered one of the best receivers in the NFL.

Although he got off to a slow start with just five catches for 67 yards (including just one catch for 4 yards against the Patriots) in the opening two games, Fitzgerald seemed to get back on track in last week’s win against the Eagles. In Arizona’s 27-6 win, Fitzgerald hauled in nine passes for 114 yards and his lone touchdown of the season.

Johnson had eight catches for 119 yards with a touchdown in Houston’s 30-10 win in the season opener.

“We know they have some great recievers,” safety Reshad Jones said. “They have a quarterback who can throw the ball around a bit. It’s a great challenge for us as a defense — especially as a secondary. We have to make the plays that are there.”

Injury updates

Both running back Reggie Bush (knee) and cornerback Richard Marshall (back) worked out in Friday’s light practice in the bubble. Bush worked with the first-team offense for the second consecutive day after leaving Sunday’s loss to the Jets just before halftime.

Marshall wasn’t at Thursday’s practice, but he participated Friday. He initially sustained the injury two weeks ago against Oakland.

“Yeah, I’m feeling good,” Marshall said. “I was just a little sore [Thursday]. I’m feeling fine.”

Both players are listed as questionable for Sunday.

‘A standard Friday’

Coach Joe Philbin said he treated Friday’s practice like a normal Friday even though the Dolphins were headed out of town a day early. The Dolphins took a plane out of Fort Lauderdale on Friday evening and were scheduled to land around 9 p.m. EDT.

The Dolphins will hold meetings at their hotel on a light Saturday in Arizona.

“This was a standard Friday practice and I thought it was good,” Philbin said. “I’ll probably look at it more on the plane. But the tempo was good, guys were moving around.”
