Without do-it-all receiver Deebo Samuel, Christian McCaffrey offered the Niners the ultimate in versatile performances, as he threw for, ran for and caught a touchdown as the Niners beat the Rams and moved to 4-4 heading into their bye week.

"I think everyone knows how good of a player he is, but I just like how consistent he is and under control in what he does," Shanahan said. "He's a very smart player, and he makes a lot of plays and stuff, but it's the consistency of how he plays his game. I feel like he was a great guy to add for us."

Cooper Kupp was down on the field after injuring his right ankle late in the Los Angeles Rams' loss to the San Francisco 49ers, but the wide receiver said "things are pointing towards dodging a bullet" with the injury.

Kupp said he feels "pretty good right now," but that he will know more after he sees how his ankle responds over the next few days. Kupp had tape wrapped around his right ankle during his postgame news conference.

"It just got rolled up a little bit," Kupp said. "Foot got caught, but I think it was able to slide out of there before there was too much damage done, and so, we'll see over these next few days how it responds."

San Francisco 49ers wide receiver Deebo Samuel has made a habit of torturing the Los Angeles Rams, but he won't be able to do it Sunday as he has been ruled out with a hamstring injury.

Samuel, who did not practice all week, suffered the injury in last Sunday's loss to the Kansas City Chiefs. 

The San Francisco 49ers have received calls on running back Jeff Wilson and are willing to listen to potential offers, sources told ESPN's Jeremy Fowler on Friday.

Wilson ranks 11th in the NFL in rushing with 454 yards, but San Francisco has a crowded backfield with the arrival of Christian McCaffrey and Elijah Mitchell close to returning from injury.

The Buffalo Bills, Denver Broncos and Philadelphia Eagles all inquired with the Carolina Panthers about a trade for Christian McCaffrey before he was dealt last week, according to a report.

Carolina traded McCaffrey to the San Francisco 49ers for a second-round pick, third-round pick and fourth-round pick in 2023, plus a fifth-round pick in 2024.

Of the Bills, Broncos and Eagles, Buffalo is believed to have been the most aggressive in pursuit of the running back.

Christian McCaffrey is expected to make his San Francisco 49ers debut Sunday against the Kansas City Chiefs, sources told ESPN's Adam Schefter.

McCaffrey's availability comes just three days after the 49ers and Carolina Panthers agreed to a blockbuster trade for the star running back and just two days after he flew to San Francisco and joined his new employer.

The 49ers have a package of plays in Sunday's game plan for McCaffrey, who has picked up what he could of the offense quickly, sources told Schefter.

The San Francisco 49ers have traded for Christian McCaffrey from the Carolina Panthers for a second, third and fourth round pick in 2023 plus a fifth round pick in 2024.

McCaffrey signed a four-year, $64 million extension with the Panthers in 2020.

In six games this season, McCaffrey has rushed for 393 yards to go with 277 yards receiving. McCaffrey has dealt with injuries in 2020 and 2021 after two massively productive seasons in 2018 and 2019.

The Niners have have been banging this drum for years: Artificial turf isn't fit for NFL games.

Sunday's win over the Panthers was marred by a paragraph-long injury report, including serious injuries to some of the team's best players. Cornerback Emmanuel Moseley may have torn his ACL, safety Jimmie Ward broke his hand, and kicker Robbie Gould and defensive end Nick Bosa left with leg injuries. And while the Niners have been bitten by the injury bug all season, Sunday happened to be their first game on FieldTurf.

"If you're not gonna mandate grass, why aren't all turf fields the exact same turf so guys get used to playing on the same turf everywhere?" asked George Kittle, who escaped from the 37-15 win unscathed. "NBA guys don't play on different wood, so what are we doing. ... I just wish we played on a surface that was similar every single week in and week out, so your body wouldn't just be dealing with different crappy turf."

Panthers coach Matt Rhule didn't want to discuss if he'd consider benching quarterback Baker Mayfield before next week's game against the Rams, but a left ankle injury could take the decision out of his hands.

Mayfield injured the ankle late in the first half when a player fell on it. He limped into the locker room with 11 seconds left and played most of the second half before former XFL star PJ Walker came on to finish the 37-15 loss to the 49ers that left Carolina with a 1-4 record.

Mayfield was wearing a walking boot when he met with reporters.

49ers defensive end Nick Bosa's pursuit of a fifth straight game with a sack to start the season ended early Sunday against the Panthers as he departed in the third quarter with a groin injury.

Bosa was the biggest loss for the Niners on a day when they saw two other key contributors leave with injuries. In the first half, San Francisco lost safety Jimmie Ward to a left hand injury and kicker Robbie Gould departed in the third quarter with a left knee injury.
