Peterson was among 11 players listed as probable on Wednesday's injury report, but he was the only one among them that didn't practice Tuesday.
Also listed as probable, meaning they are a "virtual certainty" to play, are DE Jared Allen (groin), CB Antoine Winfield (knee), LT Matt Kalil (back), S Harrison Smith (calf), S Robert Blanton (hamstring), LB Marvin Mitchell (calf), QB Christian Ponder (knee), RB Matt Asiata (knee), DT Fred Evans (knee) and WR Jerome Simpson (low back/foot).
The Vikings officially declared TE John Carlson (concussion) and S Mistral Raymond (ankle) out for the game.
Starting middle linebacker Jasper Brinkley was also added to the injury report as probable, but his absence at Wednesday's walkthrough was not injury-related.
The Bucs listed CB Brandon McDonald (ankle) as questionable. LB Adam Hayward (ankle), WR Vincent Jackson (calf), G Carl Nicks (foot) and C Jeremy Zuttah (quadriceps) are probable.
