The Chiefs elevated Powell from the practice squad Saturday, Matt Derrick of ChiefsDigest.com reports.
If Powell is active for Sunday's game against the Rams, he'll add depth to a receiver group that will be without Mecole Hardman (abdomen) and Kadarius Toney (hamstring) for the Week 12 contest. Even so, Powell will still be fifth in the pecking order at wideout, and he's more likely to see snaps on special teams than on offense.
