EDEN PRAIRIE, Minn. (AP) — The Minnesota Vikings have ruled Christian Ponder out for Sunday's game at Baltimore, because the quarterback has not yet passed all of his post-concussion tests.
Coach Leslie Frazier said Friday that Ponder will not suit up against the Ravens, with Matt Cassel starting and Josh Freeman backing him up per the plan set at the beginning of the week.
This is Ponder's third significant injury of the season. He had a broken rib that paved the way for Cassel to start against Pittsburgh on Sept. 29, and dislocated his shoulder at the end of the third quarter against Washington on Nov. 7. Ponder took a hit to the head late in the second quarter last week against Chicago.
Running back Adrian Peterson returned to practice Friday after taking the last two days off to rest his sore groin, following the pattern that has developed in the second half of the season to keep him fresh.
"No real need to burst or go 100 miles per hour today, but just something to make him feel comfortable about Sunday," Frazier said.
