KANSAS CITY – It's the final audition for several players on the roster bubble Thursday night at Arrowhead Stadium.

Here are a few items to keep an eye on:

1. No. 3 QB – The trade of Brett Hundley to Seattle puts DeShone Kizer in the No. 2 spot at quarterback, but it also will give undrafted rookie Tim Boyle some playing time against the Chiefs, perhaps his biggest workload of the preseason. Will he play well enough for the Packers to keep him on the 53-man roster?

2. The new guy – Inside linebacker Antonio Morrison, acquired in a trade earlier this week from Indianapolis, is expected to make his Packers debut. A third-year pro, Morrison comes advertised as an aggressive, hard hitter. He doesn't have much time to pick up Mike Pettine's defensive scheme, but a few game reps would help his progress.

3. Building blocks – Third-year offensive lineman Jason Spriggs and rookie receiver J'Mon Moore are two players who had their best preseason performances last week in Oakland on an otherwise forgettable night for the offense. Now they have to build on what they've done.

4. Long snappers – The competition between Zach Triner and seventh-round draft pick Hunter Bradley still has not been decided, and there's no telling if another long snapper becomes available whether or not the Packers would consider an alternative. Specialists are always competing across the league.

5. Young corners – The Packers have seen what rookies Jaire Alexander and Josh Jackson can do, veterans Tramon Williams and Davon House have done their thing as well, and Kevin King is working his way back from shoulder issues. With Lenzy Pipkins traded for Morrison, that leaves Quinten Rollins, Herb Waters, Josh Hawkins, Donatello Brown and Demetri Goodson competing for a limited, and somewhat unknown, number of spots.
