The Vikings appear to be practicing as if linebacker Anthony Barr will be playing Sunday in Pittsburgh.

Barr, who has been dealing with a hamstring injury that kept him out of practice Wednesday and Thursday of a short week, had his helmet and was taking part in warmups and special teams drills during the opening 15 minutes of Friday's practice open to reporters.

Barr could still be listed as questionable on the final injury report submitted later today.

All Vikings were present and accounted for Friday, including quarterback Sam Bradford (knee), who has been limited throughout practice this week.

Check back this afternoon for the final injury report and game-day designations for the Vikings and Steelers.
