Laurinaitis and Finnegan were joined by RB Steven Jackson (foot), S Craig Dahl (concussion), TE Mike McNeill (thigh) and C Scott Wells (knee) on the sideline. Dahl still needs to go through the league's testing procedure before being cleared to play.
On the Vikings side, cornerbacks Antoine Winfield (knee) and A.J. Jefferson (concussion) missed practice, while star running back Adrian Peterson (abdomen) was listed as a limited participant, along with six other players on the roster.
The Rams and Vikings will kick off noon CT on Sunday from Edward Jones Dome in St. Louis, Mo. The game will be televised on FOX.
