With Toby Gerhart (hamstring) out and Adrian Peterson (groin/foot) listed as doubtful, the Vikings are expected to start Matt Asiata against the Lions on Sunday in what will be the final game in the 31-year history of the Metrodome.

It would be be Asiata's second career start and second in three games. With Gerhart and Peterson out two weeks ago against the Eagles, Asiata carried the ball 30 times for 51 yards and three touchdowns in a 48-30 win.

Meanwhile, coach Leslie Frazier said cornerback Xavier Rhodes (ankle) "did OK" in practice today and will be evaluated again on Saturday. Rhodes hasn't played the past two games because of a sprained ankle. Even with the two missed games, Rhodes' 23 passes defensed leads the team by nine.

The Vikings also placed linebacker Audie Cole on injured reserve (ankle) and signed cornerback Robert Steeples as a corresponding move on the 53-man roster. Frazier announced on Monday Cole would be out against the Lions.

UPDATE: NT Letroy Guion (quadriceps) didn't practice again on Friday and is listed as doubtful. Rhodes (ankle) and CB Shaun Prater (ankle) were limited in practice and are questionable. Everyone else not mentioned above who are dealing with injuries have been listed as probable.
