Adrian Peterson will not suit up for the Vikings in Green Bay on Saturday.

The Vikings running back, who returned from a knee injury in Sunday's 34-6 loss to the Colts, did not practice this week. He was listed with both knee and groin injuries after seven touches in 12 snaps on Sunday.

The Vikings activated running back C.J Ham from the practice squad.

Ham joined the Vikings after a rookie camp tryout. He was signed to the practice squad after final cuts. The Minnesota native went to Duluth Denfeld High School and had 3,611 yards from scrimmage and 35 touchdowns in 43 games at Augustana College.

Safety Harrison Smith (ankle) and receiver Stefon Diggs (hip) are questionable to play after being listed as full participants during Friday's team activities.

Guard Brandon Fusco (concussion), fullback Zach Line (concussion) and receiver Laquon Treadwell (ankle) also have been ruled out for the Vikings.

Rookie second-round draft pick Mackensie Alexander was placed on season-ending injured reserve when Ham was promoted.

Alexander, a cornerback who was the 54th overall pick, played 13 games with no starts, six tackles and one pass defense. He was drafted for depth purposes and is considered the heir apparent to Captain Munnerlyn at the nickel slot corner spot. He was on the injury report this week because of an abdomen injury.

Snap unhappy

Treadwell has dealt with a handful of injuries during his disappointing rookie season, which has two games remaining.

A busted thumb kept him out of the Eagles game. He sat out because of an injured hamstring in Washington. Treadwell was unable to practice or play last week against the Colts because of an ankle ailment.

But the Vikings' first-overall pick has been active for nine games and has played only 80 snaps on offense, or about nine per game, the fewest in four years among 18 relatively healthy first-round receivers.

Only A.J. Jenkins, the 30th overall pick by San Francisco in 2012, played fewer rookie snaps while healthy than Treadwell, the Vikings' 23rd overall pick. Jenkins was active for only three games and saw 35 snaps for the 49ers, who traded him to Kansas City the following summer.

The 21-year old Treadwell, who has just one catch for 15 yards this season, was a healthy scratch twice in the first three games when Vikings coach Mike Zimmer said he wanted to see better practices from the rookie. He's added 47 snaps on special teams as a gunner.

Despite the unproductive season, Zimmer gave Treadwell a vote of confidence this week. "I think he's going to be a good player," Zimmer said.
