49ers Notebook: Juszczyk week-to-week; Niners work out five; Friday’s Levi’s Stadium dry run; fake crowd noise

Here are other San Francisco 49ers-related storylines that might interest you.

49ers work out five players

The 49ers worked out or plan to work out five players, according to Aaron Wilson of the Houston Chronicle. They are offensive linemen Jamon Brown, Ted Larsen, Dakoda Shepley, and Isaiah Williams, along with tight end MarQueis Gray.

News of Shepley's workout was first reported by CFL insider Farhan Lalji. The Saskatchewan Roughriders recently released him so he could pursue NFL opportunities.

News of Brown's workout was first reported on Wednesday by Vaughn McClure of ESPN.

The 49ers have been banged up both along the offensive line and at tight end, as well as other positions. That was among the reasons why Shanahan opted to switch Thursday's practice from a full session to a walk-through.

Two new names on the injury list

Shanahan added tight end George Kittle and fullback Kyle Juszczyk to the team's growing list of injured players. The latter seems to be more serious than the former. Although, Shanahan didn't sound too concerned about either.

Kittle is dealing with a tight hamstring.

"He checked out alright, but it was tight, so we took him out of there before something bad happened," Shanahan said.

Juszczyk is week-to-week with a hamstring strain. He, along with Kittle, was seen working with a trainer on a side field during Wednesday's practice.

Friday's practice to provide a dry run for the equipment staff

Head coach Kyle Shanahan shared that Friday's practice at Levi's Stadium will help provide a dry run for the 49ers equipment staff, who typically have four preseason games to work out the kinks.

"We'll have all the tablets, headsets out there," Shanahan said. "So, our guys who are in charge of doing that stuff, make sure it's all working. I doubt I use it. I'd expect it to be working on Week 1.

"All the guys who deal with that stuff are used to getting four trial runs at it. I can remember a number of preseason games where the pictures aren't working, or a tablet goes down, and we're a lot more patient there in the preseason, but they've got four games to get better at it."

Fake crowd noise at Levi's Stadium

The 49ers already announced that their Week 1 matchup against the Arizona Cardinals would be played without fans in attendance. That could mean using Levi's Stadium's speaker system to pump in fake crowd noise during the game.

"Once we do get any official word of exactly what the rules are, I think we're going to have a lot of ideas," Shanahan said. "Crowd noise is a huge effect in the NFL and that's why I truly believe home field advantage is a bigger deal in football than any other sport because the communication that's involved when an O-lineman cannot hear a snap count, it is extremely hard to block defense alignments. So, I think that's a huge advantage.

"When are we going to play the noise? How's it going to be? Right now, I'm hearing you've got to press play on the noise at the beginning of the game, and you can't turn it off till the end of the game. So, that means we're helping both D-Lines when we're at home.

"There's lots of stuff that I really don't know about yet. I've got a lot of ideas, but try not to waste too many extra thoughts when I don't know the exact parameters yet."

While the 49ers have only announced that fans are prohibited for that September 13 game, there is a strong possibility of future home games being absent of fans.
