Vikings not ruling out Adrian Peterson

It appears we're in for another week of waiting on the status of Minnesota Vikings tailback Adrian Peterson, whose high ankle sprain will prevent him from practicing Wednesday and could keep him out of Sunday's game against the Denver Broncos.

Coach Leslie Frazier told reporters Wednesday that he hopes to get Peterson back on the practice field by Friday to gauge his progress from an injury that occurred 10 days ago.

The Vikings had their second-worst offensive game of the season last Sunday with Peterson sidelined, netting 226 offensive yards and 12 first downs in a 24-14 loss to the Atlanta Falcons. Backup Toby Gerhart managed 44 yards on 17 carries, and the Vikings also handed off to receiver Percy Harvin five times.

Peterson has missed consecutive games only one other time in his career, in 2007 when he missed two games because of a sprained knee.
