The 49ers will play the Kansas City Chiefs in Arrowhead Stadium at 5:00 p.m. PT. With the position battles still continuing, here are some key players to keep a close eye on for tonight's game:
1. A.J. Jenkins
To sum it up in short, it has been a rough two weeks for the 2012 first-round draft pick in training camp. In his last preseason game, he had a catch which turned into a fumble, while two interceptions were results of balls thrown his way. In the last two practices, he has improved but still needs to show something against opposing defenses. This will be a game for him to prove himself as Jim Harbaugh said he "could be better" than how he performed last week.
2. Backup Quarterback - Scott Tolzien vs. Colt McCoy vs. B.J. Daniels
After Colin Kaepernick finishes the opening reps, the backup quarterback competition is still open and undetermined. Many believed McCoy was the leading frontrunner for the No. 2 job, but last week he had a rough outing before leaving the game with a minor shoulder injury. Tolzien showed some promise with a two-minute drill that brought the 49ers into field goal range at the end of the first half. Daniels has yet to make an appearance at quarterback as he was only seen on special teams in the preseason opener. As of right now, Daniels is the fourth quarterback on the roster and it will be interesting if he gets playing time at the QB position. Harbaugh hinted that there's a good chance that every quarterback will play if the situation of the game is right.
3. Adam Snyder
Joe Staley will most likely not play in the preseason game as Harbaugh said he wouldn't make the trip to Kansas City. With Staley out, Adam Snyder becomes the team's starting LT and he would fill in at any position if a starting offensive lineman got hurt. The former starting guard from 2011 is versatile, but can he face the quality pass rushing from a player like Tamba Hali? Snyder excelled as an interior linemen, but it is questionable on how he is at the tackle position. It will be interesting to see how well Snyder does in protecting the blindside of the quarterback.
4. Reserve Cornerback - Tramaine Brock vs. Perish Cox
Both players are trying to make an impact in the secondary and should be getting a lot of playing minutes. Brock and Cox played well in last week's preseason opener against the Broncos and there should be a close eye on both players to maintain their momentum. It's also important to see how well they do on special teams.
