The Vikings will head into Friday's light workout with no injury concerns about any of their starters.

But backup nose tackle Kenrick Ellis (ankle) missed all of practice for the second straight day and is looking less likely to play in Sunday's NFC wild-card playoff game against Seattle. That's why the team promoted rookie defensive lineman B.J. DuBose from the practice squad when tight end Rhett Ellison was placed on injured reserve on Tuesday.

The official injury report for today has been released. Running back Adrian Peterson (lower back) did not practice again, but coach Mike Zimmer and Peterson both spoke earlier and made it clear that Peterson will play and be fine in Sunday's NFC wild-card game against Seattle at TCF Bank Stadium.

Meanwhile, nose tackle Linval Joseph practiced again today. He was limited again, but Zimmer said he expects Joseph to play on Sunday. Defensive end Everson Griffen (shoulder) also was limited, but he will play on Sunday.

Fullback Zach Line practiced today and was taken off the injury report after missing Wednesday's practice because of an illness.

And receiver Adam Thielen (shoulder/low back) remains on the injury report but had full practice participation again today.
