The Vikings have another rookie from Arkansas.

With injuries mounting on their offensive line, the team has signed Grant Cook, a 6-4, 318-pound guard that can also play tackle. The Vikings released undrafted rookie defensive end Eric Latimore to make room for Cook on the 90-man roster.

Cook signed with the Packers as an undrafted rookie, but was released on July 25. Cook has been reunited with former Hogs Jarius Wright and Greg Childs, the receiving duo the Vikings picked up in the fourth round of the draft.

The Vikings need bodies up front with four of their linemen -- Pat Brown (knee), DeMarcus Love (shoulder), Kevin Murphy (heat-related illness) and Geoff Schwartz -- struggling with their health. Schwartz, who was being given a chance to compete with Brandon Fusco for the starting right guard job, has suffered a sports hernia, according to a league source with knowledge of Schwartz's magnetic resonance imaging (MRI) exam today. Schwartz could need four to six weeks or more to recover.
