The Los Angeles Rams made a pair of roster moves on Monday, activating WR Pharoh Cooper to the 53-man roster, and moving WR Cooper Kupp onto the club's injured reserve list as a corresponding move.

Cooper was designated to return earlier this week, after spending the mandated eight weeks on the IR. The return man injured his ankle Week 1 against the Raiders in Oakland.

A season ago, Cooper averaged 27.4 yards per kick return, and took one return for a touchdown. The third-year All-Pro return man is expected to resume his kick return duties if active on game day.

Kupp is moved to the list a week after the second-year receiver out of Eastern Washington tore his left ACL in a non-contact play in the fourth quarter of Week 10's game against the Seahawks.

Kupp finished his season leading all Rams' receivers with six touchdown receptions. He will miss the remainder of the season.
