With Tom Johnson out with an ankle injury and Everson Griffen not with the team, Vikings have six active D-linemen

The Minnesota Vikings got some good news before Thursday night's game in Los Angeles against the Rams with running back Dalvin Cook and Riley Reiff being active for the game.

However, Minnesota is going to be without defensive tackle Tom Johnson, who is dealing with an ankle injury. With Johnson inactive, the Vikings are down to six active defensive linemen because of Everson Griffen's absence and rookie Jalyn Holmes being declared a healthy inactive.

Cook had been limited in the past two practices, but he proved he's ready to return from his hamstring injury after sitting out last week. Cook has struggled to get going this season in his return from last year's knee surgery. He has 26 carries for 78 yards, a 3.0-yard average. Minnesota has the second-worst running game in the NFL this season at 66.0 yards per game.

Los Angeles is ninth in the league in run defense, giving up 96.7 yards per game.

Reiff's presence should help, as well. The Vikings' left tackle missed practice all week with a foot injury.

With Johnson out, Minnesota has just end Tashawn Bower and tackle Jaleel Johnson in reserve of defensive-line starters Danielle Hunter, Linval Joseph, Sheldon Richardson and Stephen Weatherly. Holmes has been inactive for each game this season.

Also inactive for the Vikings are returner Marcus Sherels (ribs), quarterback Kyle Sloter, safety Anthony Harris (hamstring) and offensive lineman Bryan Witzmann.

Surprisingly, the Rams have cornerback Marcus Peters active as he deals with a calf injury. Reports said Peters was expected to miss the game but he worked out prior and is active. He missed two days of practice and was limited on Wednesday.
