The Chiefs signed Blanton to their practice squad Thursday, Matt Derrick of ChiefsDigest.com reports.
Blanton was waived by the Commanders ahead of Tuesday's 53-man roster deadline but has found a new home in Kansas City via the practice squad. The 26-year-old tight end appeared in 11 games for the Rams last year and caught four of seven targets for 37 yards across 144 offensive snaps.
