Injured Arizona Cardinals running back Chris Johnson will be eligible to return this season, but not until late in the playoffs.
On Tuesday, the Cards placed the 30-year-old on injured reserve/designated to return after an MRI revealed Johnson suffered a fractured tibia during Sunday's game at the San Francisco 49ers. Johnson won't be eligible to return until the NFC Championship game at the earliest.
