W2W4: Green Bay Packers

GREEN BAY, Wis. -- The Green Bay Packers (2-1) play their second of two home preseason games on Friday (7 p.m. ET) against the Kansas City Chiefs (1-2).

Here are three things to watch:

1. Center of attention: All eyes will be on Corey Linsley as the rookie fifth-round pick will make his first start at center in what will be his one and only tune up before the regular-season opener a week later at Seattle. The Packers turned to Linsley after JC Tretter sustained a knee injury in last Friday's preseason win against the Oakland Raiders. Even quarterback Aaron Rodgers likely will keep a close eye on Linsley -- from the sideline. Rodgers is not expected to play in the preseason finale, which means his first game action with his new center will come against the Seahawks.

2. Backup quarterbacks: The most important job still up for grabs is the No. 2 quarterback spot. Coach Mike McCarthy would like to get Matt Flynn and Scott Tolzien equal playing time to get one last evaluation, but he does not plan to alternate them a series at a time. McCarthy said he would rather see them over extended stretches. For what it's worth, Rodgers said this week he hopes both quarterbacks stick on the roster because both help him to prepare for the upcoming opponent and assist him on game day.

3. Who sits: Last week, the Packers lost a pair of starters -- Tretter and B.J. Raji -- against the Raiders. Not that McCarthy needs any more reason to play it safe, but look for several starters to sit this one out. In addition to Rodgers, the Packers might be inclined to sit starting running back Eddie Lacy, receivers Jordy Nelson and Randall Cobb. Don't expect the starting offensive line, other than Linsley, to play much, if at all. On defense, the Packers might sit outside linebackers Clay Matthews and Julius Peppers among others.
