Rams activate WR Puka Nacua after five games out

LOS ANGELES -- The Rams activated wide receiver Puka Nacua from injured reserve ahead of Thursday night's game against the Minnesota Vikings.

Nacua is active for Thursday night's game. ESPN's Adam Schefter reported earlier Thursday that the Rams wouldn't decide until pregame warmups how much he would participate.

The Rams placed linebacker Troy Reeder (hamstring) on injured reserve in a corresponding move. Reeder, a starting inside linebacker, will be sidelined for at least four games.

Nacua, who sprained his PCL (posterior cruciate ligament) in Week 1, has missed the Rams' previous five games. The injury was an aggravation of a training camp knee injury.

The Rams have been without their top two receivers since Week 2, but Cooper Kupp also is set to return Thursday night from a sprained ankle.

Last season, Nacua set records for the most receptions (105) and receiving yards (1,486) by a rookie in NFL history. Nacua had four catches for 35 yards in the Rams' season opener before his injury.
