Arizona Cardinals running back Chris Johnson has been ruled out indefinitely due to a fractured tibia, according to a report.
The 30-year-old sustained the injury in the third quarter of his side's victory over the San Francisco 49ers when he attempted a run through the middle.
Bruce Arians's men are considering placing Johnson on season-ending injured reserve, but will wait until they receive a final diagnosis on the injury, reports Fox Sports.
Johnson has rushed for 814 yards and three touchdowns this season.
