According to Arians, Johnson has the same prognosis as injured running back T.J. Logan, who is out for 8 to 12 weeks.
Johnson, who will turn 32 on September 23, re-signed with Arizona the day before training camp started, with the understanding that his role would expand compared to last season. In two games against the 49ers last season, Johnson ran the football 46 times for 212 yards and three touchdowns.
Johnson accounted for 2,118 yards and 373 touches (293 rushes, 80 receptions) in 2016.
A fourth-year back out of Utah State, Williams has only touched the ball 103 times in four professional seasons. He has been injury prone and has played in only five of the team's 33 games since he was drafted. Kerwynn Williams, Andre Ellington, and Chris Johnson will handle the running back duties until DJ returns.
Up to that point in the game there hadn't been too much to write home about Johnson's performance.

"It's always tough seeing guys' seasons ended after Week 1", Veldheer said.
"Just relieved from the fact that I finally get a fair trial", Elliott said after the game in his first public comments about the matter.
This isn't good. The Cardinals didn't look good yesterday and they lost their best player.
Tight end Troy Niklas also cited the team's depth at running back as reason for a ray of optimism. We're going to have to put pieces together and try to make two people one, essentially. If you are wanting more from the running back spot, there are a handful of players for the taking who could break through given big opportunities.
