Toney (hamstring) didn't practice Friday, Matt McMullen of the Chiefs' official site reports.
Toney has been absent for all three of Kansas City's practices this week after leaving early in last Sunday's win over the Chargers due to his latest hamstring injury. He'll almost certainly have an injury designation upon the release of Friday's injury report, and it wouldn't be surprising to see Toney ruled out for Sunday's game against the Rams.
