In the last few weeks, things have begun to titter off for Arizona Cardinals running back Adrian Peterson. As bad, he has been dealing with a bothersome neck issue for some time.

According to ESPN, there is a growing notion that Peterson will not play on Sunday afternoon against the Tennessee Titans due to the ailment.

Arizona Cardinals running back Adrian Peterson is likely to miss his second straight game due to a neck injury, a source told ESPN's Josina Anderson.

The 32-year-old has been unable to practice at all in the last two weeks due to the injury. It is isn't expected to require surgery, but it may need him to rest for a few weeks in order for it to heal fully.

In fact, he has yet to receive any medical clearance to get back on the field.

Since joining the Cardinals earlier this season, Adrian Peterson has racked up 448 rushing yards on 129 carries with two touchdowns in six games played. Despite tallying more than 130 rushing yards in two out of his first three games with Arizona, Peterson's production had tailed off, failing to break more than 30 rushing yards in two out of the last three contests played.

If he is unable to go, backup Kerwyn Williams will likely draw the start for the second straight week while D.J. Foster will spell him in passing situations. Against the Los Angeles Rams last week, Williams notched 97 rushing yards on 16 carries.
