The Chicago Bears (1-0) host the Jacksonville Jaguars (1-0) in preseason game No. 2 at Soldier Field. The game will be nationally televised on ESPN.

1. Backup quarterback battle: Jordan Palmer received first crack at the No. 2 job in the preseason opener, but in this matchup, the plan is for the Bears to go with Jimmy Clausen once Jay Cutler is finished for the night. Palmer played fairly well in the preseason opener, but Clausen stole the show when he came in, finishing with two touchdown passes and a passer rating of 134.6. If Clausen performs similarly against the Jaguars, it’s likely the Bears take away all the suspense in this battle and name him the No. 2. Remember, Cutler hasn’t played an entire 16-game season since 2009, which makes the backup quarterback job important.

2. Linebacker play: Collectively, the group played poorly in the opener against the Eagles. But in its defense, the team was matched up against a high-octane, no-huddle offense that featured plenty of zone-read concepts that the Bears hadn’t game-planned for. Specifically, Jonathan Bostic and Shea McClellin need to play better. Considering he started nine games as a rookie, Bostic should be poised to take a major step in his development, but we haven’t yet see that. McClellin is making the transition from defensive end, and the staff remains confident he’ll progress enough that the team would feel confident about making him the starter on the strong side.

3. Zach Miller’s bid for the No. 2 tight end job: Incumbent Dante Rosario missed practice Tuesday with soreness in his calf, and if he’s held out of this matchup, Miller basically will receive the opportunity to solidify what appears to be a stranglehold on that No. 2 tight end spot. Miller caught six passes for 68 yards and two touchdowns in his preseason debut, and has since been given more repetitions with the starters when the offense goes to two-tight-end sets. Another strong showing by Miller in this game could outright win him the job, and he needs to take advantage. So far, Miller has taken advantage of every opportunity he’s been given. This game should be no different for him.
