Cardinals' Darren Fells: Suffers stinger Sunday

Fells emerged from Sunday's defeat to the Rams with a stinger, Mike Jurecki of FOX Sports 910 Phoenix reports.

Analysis:

After corralling both targets for seven yards in Week 4, Fells wasn't present at Monday's practice, indicating treatment will dominate his preparation for Thursday's game in San Francisco. If he requires a respite, Jermaine Gresham will have an opportunity to serve as the primary tight end, which could have added importance with Drew Stanton likely directing the offense due to Carson Palmer's bout with a concussion.
