GLENDALE, Ariz. -- Two days after Cardinals coach Bruce Arians said running back Chris Johnson would miss one to two weeks because of a hamstring injury, Arians upgraded Johnson's status to day-to-day.
"He's healing," Arians said. "He's had these [minor injuries] in the past, and they only lasted a few days, so hopefully it's one of those."
Johnson did not practice Monday.
Johnson hurt his right hamstring on the last play of Thursday's practice, which caused him to miss Saturday's preseason game against San Diego. Arizona plays at Oakland on Sunday.
Arizona signed Johnson on Aug. 17.
