LOS ANGELES -- The Rams put wide receiver Puka Nacua on injured reserve after all Thursday.
Nacua injured the MCL in his right knee and a toe in Sunday's victory over the Washington Commanders and is expected to sit out what coach Sean McVay called "an extended period of time."
On Wednesday, McVay had said that because of roster mechanics, the Rams would keep Nacua on the active roster. But on Thursday, the Rams pivoted so they can sign receiver Brennan Presley to the active roster and sign receiver Tyler Scott to the practice squad.
Nacua will sit out at least four games while on injured reserve, at the Arizona Cardinals, at home against the Green Bay Packers and Kansas City Chiefs, and at the San Francisco 49ers.
In seven games this season, Nacua has 70 catches for 715 yards and four touchdowns. He sat out Weeks 2 and 3 because of a hip injury.
Nacua's 70 receptions are the most through a player's first seven games of a season in NFL history, according to ESPN Research.
The Rams (5-4) also are without wide receiver Davante Adams, who has been on injured reserve since rupturing a hamstring muscle late in the Rams' Week 6 loss to the Cardinals.
