If the Broncos didn’t give C.J. Anderson a look this week, when would they?

The undrafted rookie running back from the University of California will be activated on the Broncos’ 46-man game roster for the game Sunday against Mike Shanahan’s Washington Redskins, according to multiple NFL sources.

Anderson is expected to take the game-day roster spot of Ronnie Hillman, who fumbled at Indianapolis’ 2-yard line late in the fourth quarter last Sunday to kill the Broncos’ chances of completing a comeback.

The Broncos’ running game through seven games has pretty much been Knowshon Moreno and little else, as Hillman and rookie Montee Ball have each had fumble problems.

Anderson at 5-foot-8, 224 pounds is the heaviest of the Broncos’ running backs and may be able to help on those third-and-1 plays that Moreno failed to pick up twice last week at Indy.

Anderson had a terrific performance in the Broncos’ preseason opener at San Francisco, rushing for 69 yards on 15 carries. But he suffered a sprained MCL knee injury a couple days later during a training-camp practice.

He was cleared to practice several weeks ago.
