Richard (chest) is questionable for Sunday's game versus the Chiefs, Paul Gutierrez of ESPN.com reports.
Richard didn't practice all week after suffering a chest injury in last Sunday's win over the Broncos, so he may be on the wrong side of questionable. Regardless, Devontae Booker appears to have usurped Richard as the No. 2 running back behind Josh Jacobs, so Richard isn't expected to play much if he suits up. Theo Riddick likely will handle some work on passing downs if Richard is ruled out.
