Conner, who is listed as questionable, sat out Wednesday's practice before returning for limited work on Thursday and Friday.
Conner was slowed by the injury after his first carry of the second half in last week's 29-23 overtime victory over the Las Vegas Raiders. Eno Benjamin and Darrel Williams split the workload in Conner's place for the remainder of the game, with Williams rushing for a key 1-yard touchdown during the Cardinals' fourth-quarter comeback.
Conner, 27, signed a three-year, $21 million contract to stay in Arizona this offseason. He has 17 carries for 51 yards and a touchdown this season.
