With Jamaal Charles out for the season with a torn ACL, Charcandrick West will become the main running back for the Kansas City Chiefs.

Knile Davis was presumed to be the backup, but it actually has been West receiving carries.

West took 18 snaps following Charles' injury compared to four for Davis.

"We haven't heard anything," West said, via the Kansas City Star. "They told us -- me and Knile -- we're both going to play, we both have to be ready to step up. We know our big brother went down, so it's time for us to step up."
