The Kansas City Chiefs are set to play the Atlanta Falcons on Sunday, but they will be without star running back Kenneth Walker III. Walker's status for the game was previously in question due to an injury. According to NFL insider Jordan Schultz, Walker has now been ruled out due to a groin injury.

Adam Schefter of ESPN provided an update on Walker's injury outlook for future games after the news that he was ruled out for Sunday's matchup.

“The Chiefs, in the words of a source, ‘want to give him a week,'” Schefter reported.

Walker has had a big season so far. The Chiefs are hopeful he won't have to miss too much time.
