The Los Angeles Rams officially placed dynamic wide receiver Puka Nacua and two starting offensive linemen on injured reserve Wednesday amid a flurry of moves.

Guard Steve Avila, left tackle Joe Noteboom and Nacua all will have to miss at least four games.

In corresponding moves, the Rams signed Geron Christian off their practice squad and signed fellow offensive lineman Dylan McMahon off the practice squad of the Philadelphia Eagles.

Nacua, 23, suffered a PCL sprain in his right knee Sunday night against the Detroit Lions. Nacua appeared to sustain the injury on a 6-yard catch with 6:36 left in the second quarter of the Rams’ 26-20 loss at Lions. He had four catches for 35 yards.

Avila, 24, suffered an MCL sprain during the game. The veteran Noteboom (high ankle sprain) will miss at least a few weeks and guard Kevin Dotson (lateral ankle sprain) is considered day-to-day.

The Rams also brought back veteran defensive back Ahkello Witherspoon to their practice squad. He started all 17 games for the club last year.
