The San Francisco 49ers‘ 2025 preseason is officially in the books after they downed the Los Angeles Chargers on Saturday night from Levi’s Stadium in Santa Clara, Calif., 30-23.

Along the way, the 49ers sustained several bumps and bruises. 49ers third-string left tackle Isaiah Prince sustained a knee injury, tight end Brayden Willis exited with a neck injury, quarterback Tanner Mordecai exited with an ankle injury but returned and rookie cornerback Jakob Robinson suffered a forearm injury.

Of those ailments, Robinson’s sounded like the most pressing according to 49ers head coach Kyle Shanahan’s postgame remarks. Shanahan said he thinks Robinson broke his forearm.

“It was at the end of the game, but I think he broke it. You know, he didn’t return… I just got that before I came in. We’ve got to X-ray it for sure and everything, but that’s what it sounded like,” Shanahan said.

Shanahan was also asked if receiver Jauan Jennings was in jeopardy of missing Week 1.

“If it doesn’t heal, yes. But, I expect him to be back, I think he should be back from it, but you never know with calves,” Shanahan said.

Shanahan was asked if he expected Jennings’ calf injury to be this severe when he re-aggravated it in practice.

“I’m not a doctor, so, like I said, calves take time. You never know with calves,” Shanahan said.

Shanahan also said that he expects 49ers wide receiver Jacob Cowing to be out for a while with his hamstring injury.

“Yeah, he pulled it fully. It was the same one, so I think they told me like six weeks to start,” Shanahan said.

Shanahan also revealed that linebacker Tatum Bethune didn’t play because of a sore back.

On a positive note, Shanahan said that running back Jordan James is nearing a return, though his status remains week-to-week. Shanahan also said he thinks rookie defensive end Mykel Williams and rookie defensive back Upton Stout back to practice this next week.

“Really hoping to get those guys back. They haven’t guaranteed it to me, but I think we will. But, I won’t know that officially until tomorrow. I know a lot of them had workouts today and that’s something we’ll discuss tomorrow when we come in,” Shanahan said.
