The decision came as a surprise after the Chiefs activated him off injured reserve Monday, swapping him onto the active roster in favor of placing wide receiver Mecole Hardman on IR.
Edwards-Helaire had already lost his starting job earlier this season to rookie Isiah Pacheco before suffering a high ankle sprain in Week 11 against the Los Angeles Chargers. He missed the remainder of the regular season and the Chiefs' two playoff games while recovering.
The Chiefs' running back depth chart for the Super Bowl will be Pacheco No. 1, Jerick McKinnon No. 2 and Ronald Jones No.
