According to Daily Norseman and 1500 ESPN Twin Cities, tight end Kyle Rudolph and cornerback Chris Cook both missed practice Sunday after suffering concussions in the second quarter of Friday's preseason contest with the Buffalo Bills. Neither Rudolph nor Cook failed any of the concussion tests while being evaluated by team physicians, according to ESPN's Kevin Seifert, however both players still are being held out of football activites for precautionary reasons.

Rudolph is entering his second NFL season after being selected by the Minnesota Vikings in the second round of the 2011 NFL Draft. He played 15 games last season, finishing with 26 receptions for 249 yards and three touchdowns. Cook, the second-round pick of the Vikings in 2010, is coming off a tumultuous season in which he missed 10 games due to his involvement in a domestic violence case. Cook has stated his intentions to "earn his teammates trust" and be "a contributing factor on the team". Cook has played an average of only six games per season.

Other players who missed practice with injury are offensive lineman Geoff Schwartz, tight end John Carlson, wide receiver Kamar Jorden and linebacker Solomon Elimimian.
