Chris Johnson goes back to Arizona to fill out backfield

The Arizona Cardinals are re-signing veteran running back Chris Johnson in the wake of the serious injury to star David Johnson.

The Cardinals released Chris Johnson in their final roster cuts this year.

ESPN reported Tuesday that David Johnson would undergo surgery on his dislocated left wrist and would be sidelined two to three months.

David Johnson, an All-pro selection at the “flex” position last season and considered among the best running backs in the league, was injured late in the third quarter of Sunday’s season-opening 35-23 loss at Detroit when he made a catch and was hit hard at the 3-yard line. The next and final time he touched the ball he fumbled at the Arizona 10-yard line to set up a Lions touchdown.

Chris Johnson knows the Cardinals offense well because he spent the last two seasons with the team. Chris Johnson, who missed nearly all of last season with a knee injury, rushed for

814 yards for Arizona two years ago.
