Rader reverted to the Steelers' practice squad Monday, per the NFL's official transaction log.
Rader logged 12 snaps on offense and 12 snaps on special teams in the first NFL action of his career. The Pittsburgh native will reside on the practice squad for the time being, and he could be elevated again if Eric Ebron's stint on the COVID-19 list keeps him out for Sunday's wild-card game against Cleveland.
