Cowing played three snaps -- all on special teams -- in Sunday's 23-17 loss to the Vikings.
The rookie fourth-round pick has been active for both of the 49ers' first two games of the season, but he has yet to see any use on offense. With top wideout Deebo Samuel (calf) trending toward an absence this Sunday versus the Rams, Cowing will move up a spot in the pecking order at receiver, though he still appears to be behind all of Brandon Aiyuk, Jauan Jennings, Chris Conley and Ronnie Bell.
