49ers sign free agent RB Zamir White

Buccaneers WR Emeka Egbuka limped off with athletic trainers. Was examined on the sideline table for a while. Hard to see exactly what’s up from where we are but he’s still on the table and hasn’t returned.

Garafolo later followed up that, "Egbuka, with both cleats off, just walked back to the sideline to watch the rest of practice." Considering he came back out to the sideline without help, we shouldn't put a ton of stock in a significant injury. For now, he remains a fringe WR2/3 unless we hear something more dire here.

49ers running back Christian McCaffrey missed practice again Tuesday. Offensive coordinator Klay Kubiak attributed McCaffrey’s absence on Monday to tightness, with nothing more specific.

Coach Kyle Shanahan, though, said he is not concerned by McCaffrey’s current setback.

“No,” Shanahan said, via David Bonilla of 49erswebzone.com. “My concern would be him toughing through tightness, like a lot of people do, and then hurting something bad, and then pulling something, which then, it could be a month. That would be our concern, so once we hear him talking a certain way, Christian’s a guy who needs to get prepared for Week 1."

As the story points out, the concern is McCaffrey had calf tightness during the 2024 training camp that carried into the season. He played only four games with what was later announced as Achilles tendinitis and a separate injury to his posterior collateral ligament. There is no reason to panic just yet, but it's easy to understand why fantasy owners may be paying close attention to this situation. CMC is 30 and led the league last year with 413 touches.

Rams WR Puka Nacua, who left practice while walking with a trainer, is dealing with minor soreness in his groin, I'm told. The team is just being cautious.

Looks like Matthew Stafford was right. The Rams will likely make sure Puka is back to full strength, so owners shouldn't be shocked if he's a non-participant in practices - especially the joint ones the Rams are doing with the Cowboys.
