Kyle’s update, 3:25 p.m.: The first injury report of the season was just released:
Did not practice
WR Brandon Aiyuk (hamstring), WR Deebo Samuel (foot), CB Jason Verrett (hamstring)
C Ben Garland (ankle)
Warner wasn’t listed, so that’s good. As for Arizona:
Did not participate
T Josh Jones (ankle)
Limited Participation in Practice
WR Larry Fitzgerald (not injury related), WR DeAndre Hopkins (not injury related), TE Maxx Williams (ankle)
Kyle Shanahan spoke to the media Wednesday before practice. He announced who the team captains for the San Francisco 49ers are. Shanahan said the team voted on Saturday. This year, you’re allowed to have eight captains. The Niners had five last year.

LB Fred Warner
CB Richard Sherman
Shanahan said there is room for one more. I wonder if there will be an honorary captain in each game. That’d be a nice incentive for the players.
On the injury front, Shanahan said both wide receivers Brandon Aiyuk and Deebo Samuel have a “small chance” of practicing on Wednesday. He said, “he’d be surprised” if they were out there. As of today, I would guess that Aiyuk plays, and Samuel doesn’t. Then again, Samuel released this “hype” video on his Instagram on Tuesday.
Warner, who came off the COVID-19 list earlier on Wednesday, is back, and Shanahan said, “he’s good to go.”
Jason Verrett is out with a hamstring injury and is unlikely to play on Sunday. Center Ben Garland will return to practice, though he’ll be limited. That’s the biggest news of the day, to me. If the 49ers can get Garland on the field for Week 1, that’d be huge. The official practice report will come out at 3:30 p.m. PT.
One of the biggest talking points has been the air quality in the Bay Area. Shanahan said, “I feel like I’m in the Book of Eli. It looks like an apocalyptic state out there.” For Sunday’s game to be canceled, the air quality would have to be higher than 200. The AQI, as of around noon PT on Wednesday in Santa Clara, was at 54. While the sky is orange, there were practices during training camp that were much worse. On Wednesday, I was there; the AQI was as high as the 120s.
The crowd noise has been a big talking point. Shanahan said there is a league-wide mandate for crowd noise that’s set at 70-75 decibels. Some of the loudest crowds in the NFL are upwards to 140 decibels, nearly twice the volume level.
