With that out of the way, general manager Ted Thompson, coach Mike McCarthy and the personnel and coaching staffs must reduce the 75-man roster to 53 players by 3 p.m. (Central) on Saturday.
The regular season kicks off on Sept. 12 at Philadelphia.
"We're ready. We have no choice. We're ready," coach Mike McCarthy said.
If this were a regular-season game and if the core players had been in the lineup, these stats would give McCarthy pause: 4-of-15 on third down, 0-of-4 on fourth down and 1-of-4 in the red zone. The 433 yards equated to one touchdown and two field goals.
With a few exceptions, the Packers' starters played only one series. The No. 1 offense, with Matt Flynn at the helm, went three-and-out and the No. 1 defense held after the special teams allowed a 46-yard punt return.
Green Bay trailed 14-0 with 3:46 remaining in the first half, with the offense going three-and-out on all four of its first-quarter possessions. But Flynn's 30-yard completion to Patrick Williams on third-and-11 set up a field goal just before halftime. The Packers then pulled within 14-10 early in the third quarter, thanks to Flynn's 77-yard strike to a wide-open Brett Swain and Kregg Lumpkin's 1-yard dive into the end zone.
The Packers had a shot to win the game. After Mason Crosby's 41-yard field goal pulled them within 17-13, his perfect onside kick sent the offense back onto the field from its 44-yard line. But on third-and-8 from the Chiefs' 21, third quarterback Graham Harrell threw low to tight end Tom Crabtree and on fourth down he threw behind fullback John Kuhn.
The Packers got a final shot, starting from its 30 with 1:53 to go. The drive was jump-started with Harrell's 21-yard completion to Charles Dillon, but on fourth-and-2 from the Chiefs' 29, Dillon dropped a well-thrown slant.
