The Vikings offensive line was intact again during Friday's practice, a good sign ahead of Sunday's NFC North opener against the Detroit Lions.

Right tackle Mike Remmers will play against the Lions after being held out of Thursday's practice and limited Friday due to an illness. He was not given a game designation on the team's final injury report.

The only Vikings player ruled out Sunday is quarterback Sam Bradford. Bradford's troublesome left knee will keep him out for a third straight game with his injury appearing to be more of a week-to-week recovery than day-to-day, as head coach Mike Zimmer initially suggested.

Swing tackle Rashod Hill is questionable to play against the Lions after he injured his knee this week. He did not practice Friday.

For the Lions: Six players are questionable: DE Ezekiel Ansah (knee), LB Jarrad Davis (concussion/neck), C Travis Swanson (ankle), S Tavon Wilson (shoulder), WR Kenny Golladay (hamstring) and S Don Carey (knee).

Some more personnel notes: the Vikings have done due diligence on available tight ends, bringing in four free agents for private workouts this past week, according to a source. That includes former Cowboys second-round pick Gavin Escobar, who was last with the Chiefs this summer.
