Williamson watching

Wide receiver Troy Williamson (concussion) was a spectator for the second straight day during the early portion of practice and seems unlikely to play in Sunday's game against Detroit.

Safety Tank Williams (knee) hasn't practiced all week and almost certainly is out.

Other players missing during the portion of practice that was open to the media were linebacker Dontarrious Thomas (groin) and defensive end Kenechi Udeze, who missed Wednesday to witness the birth of his baby daughter.

The Vikings must declare the status of all players on their afternoon injury report so check back later for an update.
