If Johnson were to be placed on the IR list, it would mean he would miss at least eight weeks of action before he would be eligible to return to the active roster.
No team took a harder hit in Week 1 than the Cardinals.
Johnson totaled 1,239 rushing yards and 20 touchdowns last season. He's an all-purpose threat, logging 293 carries and 80 receptions.
In addition, the Cardinals released tackle Ulrick John, re-signed tackle Givens Price to the practice squad and released cornerback Ryan Lewis and running back James Summers from the practice squad. Logan is expected to miss up to 12 weeks of action. Foster off the Patriots' practice squad and will re-sign Chris Johnson, who they cut September 2, a source confirmed to ESPN on Tuesday.More news: US calls for UNSC meet over North Korea draft resolution
Last season, Chris Johnson played in only four games for the Cardinals, carrying 25 times for 95 yards. Quarterback Carson Palmer struggled in his 2017 debut, throwing three interceptions while completing 27-of-48 (56 percent) with two touchdowns.
The Arizona Cardinals are adding running back depth by signing Arizona State and local high school product D.J. Foster, as first reported by NFL Network's Ian Rapoport. If he does return, the time table would be early to mid-December.
O'Brien pulled Savage after he lost two fumbles - one that was returned for a touchdown - and threw for just 62 yards as the Jaguars built a 19-0 lead by halftime. Against the Carolina Panthers on Sunday, they gave up only 116 yards on the ground.
All three of the Texans' tight ends suffered concussions in Sunday's loss to the Jacksonville Jaguars, and Fiedorowicz suffered his second concussion since the start of the preseason.
