The first preseason game for the 49ers is only one day away.

With this, the fans can get a first-hand taste of how the roster is looking. However, there are a few players to watch during this exhibition against the Chiefs.

Brian Hoyer

The 49ers’ new quarterback is back in Shanahan’s system. From what people are reporting from San Francisco’s camp, Hoyer is doing incredible work with the deep ball and being comfortable in this familiar scheme.

It will be interesting to see how well he can face off against a secondary like the one in Kansas City with guys such as Peters and Berry. He’s going to need to stave off the likes of Ford and Houston in the pass rush.

Let’s see if Shanahan’s plan for the quarterback system goes through the way he’s planning.

Carlos Hyde

Much has been said about Hyde’s fit into the 49ers’ new offensive scheme. So far, he’s been a natural fit into Shanahan’s system.

He’s gone from a possible surprise cut/trade to remaining the starting running back. He should look to have a big game during the first quarter of this game.

Solomon Thomas

The Stanford product didn’t become an official part of the 49ers until just before training camp began. He missed most of the offseason workouts because of the league’s rule for draft picks to stay in school until the semester is over.

However, while he wasn’t in workouts, he was with some of the best pass rushing talents in league history. Talented pass rushers, like Warren Sapp, DeMarcus Ware, and Von Miller.

He’s currently not listed as the starter, but look for that to change once the preseason is over.

Reuben Foster

The 31st overall pick is arguably having the best training camp of anyone on the roster.

He’s the only rookie on the roster that’s listed as a starter, and if you’re paying attention to practices, it’s not hard to see why. Not only is he showing off his skills in run defense, but he’s intercepted anything thrown his way.

Expect big things from the Alabama talent.

Keith Reaser

With Dontae Johnson being out with a concussion, Reaser will have to fill in as the starter.

The two of them are currently in a competition for the starting cornerback position. If Reaser impresses, then he can catapult his way into the starting defense.

The team desperately needs someone to fill in for the void left by Tramaine Brock. Hopefully, Reaser will be the guy to take over.
