There is optimism Christian McCaffrey may be able to return from Achilles tendinitis as early as next month, the San Francisco 49ers star having missed the entirety of the season to this point because of a nagging injury that may inadvertently have been self-inflicted.

McCaffrrey, the reigning Offensive Player of the Year, has been unavailable for each of the Niners' first four games and must miss at least one more after being placed on injured reserve following San Francisco's season-opening win over the New York Jets.

Head coach Kyle Shanahan has stated the team's desire to ramp up McCaffrey's conditioning work this week with a view to him getting back on the field.

But the 49ers have little need to rush him back given how well backup Jordan Mason has performed in his stead, with the risk of being too hasty magnified by how McCaffrey's dad believes he suffered the injury.

McCaffrey has consistently been lavished with praise by teammates and coaches alike for his extraordinary preparation. The most well-rounded back in the league, McCaffrey's intensity in preparing himself both physically and mentally is arguably his greatest trait, but in this instance it may well have been his undoing.

“Tendinitis is an over-training injury, meaning you’re training too hard or doing too much, and it turns into tendinitis,” Ed McCaffrey told The Ross Tucker Football Podcast.

"If I would say that Christian has a weakness, it’s that he sometimes has to protect himself from himself, in terms of training too much and doing too much."

General manager John Lynch and Kyle Shanahan each recently confirmed McCaffrey has been dealing with bilateral tendinitis, meaning he has it in both legs.

“If you have tendinitis, you have tendinitis,” Ed McCaffrey added. "I think of it as tennis elbow. You see tennis players get it, and they can’t play tennis for a while until it heals up.

"He has that in his Achilles. It started with one, then it creeps into your calf and you start overcompensating and then you start feeling it in the other one. It’s just tendinitis. It just means it’s very, very sore."

McCaffrey recently traveled to Germany for treatment on the injury, though Shanahan would not reveal the nature of that treatment.

"He trusts his 49ers training staff,” Ed McCaffrey explained. "But when the prescription is just to rest, he’s going to go out and get other professional opinions from people around the world."

McCaffrey's injury may lead the 49ers to rest him more often if and when he does return, the former Carolina Panther having spent his offseason hard at work after racking up a league-high 339 touches in 2023.

And Ed McCaffrey conceded his son might look to alter his training regimen next year after suffering this setback in the same offseason that saw the 49ers back him to continue to stay healthy and thrive into his 30s by inking him to a contract extension. 

“It worked last year, but this year maybe he overdid it a little bit in the offseason and came in and got injured,” said Ed McCaffrey. “But you never really know. Maybe it would’ve happened anyway, but that’s part of his process.

“He’ll go back and reevaluate everything. Knowing how he is, he’ll reevaluate every day of the offseason from (this) year and try to figure out, ‘How do I change it so I show up ready to go (next) year.’”
