The Rams waived Blanton on Tuesday, per the NFL's transaction log.
Blanton was signed by the Rams as an UDFA out of Missouri in 2019. He was bumped up to the active roster for a short period during his rookie season but has spent the majority of his time on the Rams' practice squad. If he clears waivers, the 25-year-old could be a candidate for the practice squad once again.
