EDEN PRAIRIE, Minn. -- Kyle Rudolph and Chris Cook were spectators as the Minnesota Vikings resumed practice on Sunday, two days after both departed in the second quarter of an exhibition game against Buffalo with concussion symptoms.
Frazier declined to speculate about whether either or both might be held out of Friday's third preseason game against San Diego as a precaution.
Asked if either player has failed any post-concussion tests, Frazier said, "No. Up to this point, everything has gone smoothly. Whatever they have to get done (Monday), after that, we'll know exactly where things are going. But so far, everything's been positive."
Carlson hasn't practiced since he suffered a Grade 2 strain of the medial collateral ligament in his right knee on July 31. He "is still making progress," according to Frazier, who left open the possibility of Carlson making his preseason Vikings debut on Friday.
"We're going to see how he does from day to day and make a determination about whether or not we want to try to play him in this ballgame or not," Frazier said.
Also sitting out were: guard Geoff Schwartz (sports hernia surgery), receiver Kamar Jorden (hand) and linebacker Solomon Elimimian, who had an MRI that came back negative on the troublesome hamstring that kept him out of Friday's game.
Fullback Matt Asiata was absent because of a death in his family.
Nose tackle Letroy Guion (knee) had a helmet and appeared to be planning to participate in some portion of practice. So were halfback Jordan Todman (ankle), tackle DeMarcus Love (pectoral) and safety Robert Blanton (hamstring), who all sat out against Buffalo.
Frazier said all four have a chance to play on Friday.
Sunday's practice was the Vikings' first at their Winter Park headquarters since minicamp in June. Reporters only are allowed to watch the walkthrough portion of practice for the rest of the season.
