(Reuters) - Arizona Cardinals running back David Johnson has a dislocated wrist and is likely headed to injured reserve, coach Bruce Arians said Monday.
Johnson's injury could require surgery, Arians said.
The coach added that the initial prognosis for Johnson is the same as it was for rookie running back T.J. Logan, who was expected to miss 12 weeks after suffering a dislocated wrist in early August.
If the 25-year-old Johnson goes on injured reserve, he would be required to miss eight weeks.

Johnson exited Sunday's 35-23 loss at the Detroit Lions in the third quarter and underwent an X-ray. He was diagnosed with a sprained wrist and underwent further testing Monday.
Johnson appeared to get injured while making a 24-yard reception in the third quarter. He returned on Arizona's next possession but fumbled on his next carry, which was recovered by the Lions.
Last season Johnson totaled 1,239 rushing yards and 20 touchdowns. He also led the NFL with 2,118 all-purpose yards while averaging 4.2 yards per carry and 11 yards per reception.
Without Johnson, the Cardinals could turn to Kerwynn Williams and Andre Ellington in the backfield while also considering signing a free agent running back.
