49ers Rookie Buzz Meets Injury Reality — Latest Updates from Training Camp
The San Francisco 49ers may have a lot to be excited about this preseason, but one of their most intriguing young prospects has yet to show his skills under the game-day spotlight. Rookie cornerback Upton Stout, who’s been turning heads in camp, was noticeably absent from San Francisco’s preseason opener against the Denver Broncos.
That absence wasn’t a coaching decision based on performance—it was precautionary. Head coach Kyle Shanahan revealed that Stout had been dealing with calf tightness, and the team decided to play it safe rather than risk aggravating the issue. For a rookie generating as much buzz as Stout, sitting out isn’t ideal, but the 49ers are focused on the long haul.
The Caution Continues
On Monday, that cautious approach carried over into practice. Shanahan addressed reporters with updates not just on Stout, but also on wide receiver Jacob Cowing and cornerback Renardo Green.
“We were hoping Upton could go today,” Shanahan explained. “It was feeling too sore, so we’re being safe with him. I’d be surprised if he goes tomorrow, but hopefully, he’ll be back by the Raiders practice.”
Shanahan also added, “Jake had a really good day today, hit all his times, so he’ll get out there tomorrow. Renardo didn’t, so we’ll be safe with him and probably hold him this week.”
It’s a mix of good and bad news—good for Cowing, who appears ready to hit the field after hamstring trouble, but a setback for Green, who’s still nursing his own hamstring injury.
More Injury Notes from the 49ers Camp
While Stout’s situation is frustrating for fans eager to see him in game action, he’s not the only 49er dealing with setbacks. Shanahan shared a handful of other injury updates on Monday, and some of them could impact early-season depth.
-
Jordan Watkins, a rookie wide receiver, is now expected to miss about a month after suffering an ankle sprain. That timetable keeps him out of the rest of the preseason and possibly the opening weeks of the regular season.
-
The team also provided a much-anticipated update on Brandon Aiyuk, who’s been rehabbing from a serious knee injury.
The Aiyuk Watch
Aiyuk’s situation has been one of the biggest question marks heading into this season. Last year, his promising campaign came to a screeching halt in Week 7 against the Kansas City Chiefs when he tore both his ACL and MCL. Recovery from such a devastating injury isn’t a quick process, and while the 49ers have been careful not to rush him, Monday’s update gave fans a sliver of hope.
Shanahan said there’s a “potential” timeline that could see Aiyuk back by Week 6 of the regular season. That’s still subject to change, but it’s the most concrete projection the team has offered so far.
Getting Aiyuk back anywhere close to midseason would be huge for San Francisco’s passing attack. His chemistry with quarterback Brock Purdy and his ability to stretch the field are critical elements of the 49ers’ offensive game plan.
Cowing’s Return Could Be a Spark
One positive takeaway from Monday’s injury rundown is Jacob Cowing’s progress. The rookie receiver’s hamstring injury had limited him, but hitting all his timed sprints in practice suggests he’s nearly ready for live action. With multiple receivers sidelined, his return could give the 49ers a needed boost in the preseason—and give him valuable reps with Purdy and the rest of the offensive unit.
Cowing’s speed and quick route execution could make him a sleeper candidate to break into the rotation, especially if Aiyuk’s return is delayed or Watkins’ recovery lingers beyond the initial projection.
The Bigger Picture: Why Precaution Matters
Some fans might question why the 49ers are being so cautious with their rookies and key contributors in the preseason. The answer is simple: the team has been down this road before. Early-season injuries have derailed promising campaigns in the past, and the organization has learned that getting players to September healthy is far more important than winning an August exhibition.
With a roster built for a Super Bowl run, Shanahan isn’t going to risk long-term availability for short-term preseason evaluation. Stout’s calf tightness might not sound like much, but if mishandled, it could lead to a lingering issue—something the 49ers want to avoid at all costs.
All Eyes on the Raiders Matchup
San Francisco’s next chance to get a look at its depth comes Saturday at 1 p.m. PT, when they face the Las Vegas Raiders in their second of three preseason games. The matchup will be broadcast nationally on the NFL Network, giving fans across the country a chance to check out the 49ers’ rookies and bubble players.
The Raiders’ joint practices with San Francisco could also serve as a key evaluation period for guys like Stout—assuming he’s healthy enough to participate. Shanahan’s hope is to have him back on the field by then, which would give the rookie corner a chance to test himself against different offensive looks.
What’s at Stake for Stout
For Upton Stout, every missed practice rep and preseason snap is a missed opportunity to prove himself. While training camp buzz has been encouraging, live-game reps are the true test for rookies trying to cement their place in the depth chart.
If Stout can return in time for the Raiders game or the joint practices, he’ll have the chance to show his coverage instincts, tackling ability, and composure under pressure. Until then, the coaching staff will rely on his mental reps, film study, and walkthrough participation to keep him sharp.
Injury Rundown Recap
To sum it up, here’s where things stand after Monday’s updates:
-
Upton Stout (CB) – Calf tightness, day-to-day; possible return for Raiders practices.
-
Jacob Cowing (WR) – Hamstring, cleared for return after strong practice showing.
-
Renardo Green (CB) – Hamstring, likely out for the week.
-
Jordan Watkins (WR) – Ankle sprain, out about a month.
-
Brandon Aiyuk (WR) – ACL/MCL recovery, potential Week 6 return.
The Final Word
Preseason is about preparation, evaluation, and—most importantly—survival. The 49ers are walking the fine line between getting their players ready and keeping them healthy for a long season ahead.
Fans may have to wait a little longer to see Upton Stout in live action, but if that patience pays off with a healthy, confident rookie ready to contribute in the regular season, it’ll be worth it. For now, the focus shifts to Saturday’s clash with the Raiders, where San Francisco hopes to get a better look at its emerging talent while keeping its stars out of harm’s way.
