Frazier said the Vikings will have a better indication about the progress of Peterson, who has sat out the last two games, once they return to practice Wednesday. He also noted that Ponder's injury was the one the Vikings are "most concerned about" this week, before adding that trainers told him the rookie "should be fine" for this Sunday's game against Detroit.
"Christian was probably the guy who you were most concerned about, he has a hip pointer so we will have to see how he progresses as the week goes on," Frazier said. "He took a hard shot early in the game, and was able to finish the game, but it did inhibit some of his movement."
