Well, for folks thinking the last practice squad spot was for when the 49ers sign Crabtree and demote somebody, that theory can go out the window.  The 49ers announced today that they have added 24-year old guard Drew Radovich to the practice squad.  Radovich (6-5, 305) spent the 2008 season with the Minnesota Vikings.  He was inactive for the first six games of 2008, and was placed on Injured Reserve on October 13.

I couldn't find a scouting report on Radovich, but what I did find was that he was a guard at USC who dislocated his shoulder last year.  He was relatively low on the Vikings depth chart.
