Mumpfield did not catch his only target during the Rams' 27-7 loss against the 49ers in Week 1.
Mumpfield lined up for 16 of the Rams' 61 offensive snaps in Week 1, and he played six snaps on special teams. As long as two-time Pro Bowler Puka Nacua and veteran Davante Adams are available, there likely won't be room for any other Rams wide receivers to draw many targets.
