Sprained ankle continues to keep Adrian Peterson out of practice

Sprained ankle continues to keep Adrian Peterson out of practice

Adrian Peterson sat out Thursday's practice because of a sprained left ankle, although the Minnesota Vikings running back is expected to get out of a walking boot and perhaps attempt to practice Friday.

Coach Leslie Frazier said Wednesday that if Peterson can't practice Friday he will be ruled out for Sunday's game at Atlanta. The Vikings did not have media access on Thursday and had a short work day so players could get home to spend Thanksgiving with their families.

Peterson suffered a Grade 1 high ankle sprain and ligament damage in the first quarter of Sunday's loss to Oakland and did not return. That's a more serious injury than a regular sprain, and the Vikings' 2-8 record probably eliminated any thoughts about letting Peterson play without practicing. Peterson was put in a walking boot after Sunday's game.

Barring a startling recovery, backup Toby Gerhart will take over the starting role against the Falcons, with Lorenzo Booker and receiver Percy Harvin splitting time behind him.

The Vikings remained shorthanded with tight ends Kyle Rudolph (quadriceps) and Visanthe Shiancoe (hamstring) missing practice for the second day in a row. There is a chance the team will promote undrafted rookie Allen Reisner from the practice squad.

Also missing practicing again was safety Husain Abdullah (concussion).

Quarterback Christian Ponder was limited for the second day in a row in practice because of a knee injury, but an NFL source said the problem won't stop him from playing on Sunday.

Linebacker Erin Henderson (hamstring), guard Anthony Herrera (knee) and Harvin (ribs) continued to be limited.

Defensive tackle Christian Ballard (hamstring), left tackle Charlie Johnson (Achilles') and safety Jamarca Sanford (shoulder) remain on the injury report but have not missed any practice time this week.
