fifth-round pick

The Rams traded for cornerback Roger McCreary, star receiver Puka Nacua is expected to return for Sunday’s game against the New Orleans Saints and receiver Tutu Atwell will spend at least four games on injured reserve.

All of those moves were announced by the Rams or discussed by coach Sean McVay on Monday as the Rams returned from an off week.

With the NFL trade deadline approaching next week, the Rams acquired McCreary, 25, and a conditional 2026 sixth-round pick from the Tennessee Titans in exchange for a conditional 2026 fifth-round pick.

McCreary, a 2022 second-round pick from Auburn, has three career interceptions, including one this season. He is expected to provide depth to a cornerback group that lost Ahkello Witherspoon early in the season because of a broken collarbone. Witherspoon, who has been doing some individual work, was expected to be sidelined 12 weeks.

McVay said veteran Darious Williams also suffered a shoulder injury in the Rams’ Oct. 19 victory over the Jacksonville Jaguars in London.

So McCreary, who is in the final year of his rookie contract, could fortify a position group that includes Cobie Durant and Emmanuel Forbes Jr. Safety Quentin Lake has played as a slot cornerback and hybrid linebacker.

The Rams played against McCreary and the Titans in Week 2.

“We were looking to be able to add some depth,” McVay said, according to a transcript of a videoconference with reporters. “He was a guy that we respected from playing against him earlier this year.”

Nacua sat out against the Jaguars because of a high ankle sprain he suffered during an Oct. 12 victory over the Baltimore Ravens.

McVay said he expected that Nacua would practice this week and play against the Saints.

Nacua ranks fourth in NFL with 616 yards receiving.

“We do expect him to be back on Wednesday and expect him to play this week unless there are setbacks,” McVay said.

Atwell, who signed a one-year, $10-million contract before this season, played only 10 snaps against the Jaguars after sitting out against the Ravens because of a hamstring injury. He has four catches for 164 yards, including an 88-yard touchdown.

McVay said offensive tackle Rob Havenstein also is expected to return this week from an ankle injury that has sidelined him for three games.

The Rams are 5-2 heading into their game against the Saints (1-7) at SoFi Stadium.

Receiver Konata Mumpfield made multiple plays. So did running back Jarquez Hunter and other Rams rookies during training camp and a joint practice with the Dallas Cowboys.

A true evaluation about their progress, however, cannot be completed by coach Sean McVay and his staff until the first-year players perform in a live-tackling situation.

The first opportunity for rookies and others to truly demonstrate that they are worthy of regular-season roles comes Saturday when the Rams play the Cowboys in a preseason game at SoFi Stadium.

But the most notable development for the Rams will probably occur hours before kickoff.

Quarterback Matthew Stafford, sidelined during training camp because of an aggravated disc in his back, is scheduled to go through his first significant passing workout at the Rams’ facility in Woodland Hills. McVay said the 17th-year pro would begin practicing next week.

McVay does not play starters or other significant players during preseason games, so veteran backup quarterback Jimmy Garoppolo will not play.

Tight end Terrance Ferguson, a second-round draft pick, probably won’t play because of a hamstring issue that has sidelined him for the last week.
