Cardinals running back David Johnson gets in some running before the Tampa Bay game.

Bruce Arians said he doubts running back David Johnson will be able to return this season because of his wrist injury, but Johnson said Wednesday he hasn't given up hope – and that the Cardinals' record would not be a factor for him.

"I just really want to get back on the field," said Johnson, who has been on injured reserve since getting hurt in the season opener. "My biggest thing is to continue to play the sport that I love no matter what the (team's)

record is. I'm missing it so much, being out there, playing with my teammates, my brothers, I'm just trying to get back as soon as I can."

After his record-setting 2016 season came to a crashing halt with a knee injury in the season finale, Johnson has suffered significant injuries in each of the last two regular-season games he has played. That could hold weight for the team, with General Manager Steve Keim making the ultimate decision whether to bring Johnson back off of IR.

Even Arians said "ask the doctors" on Tuesday when it came to an official Johnson prognosis, although the coach was bluntly pessimistic. Johnson, however, said he remains "wide open" in terms of his optimism.

"I still have this cast on, and who knows what's going to happen?" Johnson said. "I don't know what my wrist is going to be like until my cast is off, and I still have to do rehab, so who knows."
