GLENDALE, Ariz. -- It's 1:49 a.m. back home in Wisconsin as I write this from the press box at University of Phoenix Stadium, but since the preseason-game-that-wouldn't-end didn't in fact end until 12:28 a.m. Central time, we thought a few notes from the Green Bay Packers' 44-37 victory over the Arizona Cardinals would be in order.

 > Wide receiver Greg Jennings said he OK after the game, although he said he did suffer a concussion and lost consciousness after being sandwiched between two Cardinals defenders on a 25-yard completion during the first quarter.

 Jennings caught the ball between Arizona cornerback Bryant McFadden and safety Aaron Francisco, who converged on Jennings just as he caught the ball. Although it initally appeared that McFadden and Francisco bore the brunt of the collision, Jennings stayed on the turf motionless as the two defenders rose to their feet. Jennings eventually sat up, then walked off the field under his own power, with team doctor Patrick McKenzie's arm around his waist.

 "I just got a little concussion. I'm good to go," Jennings said as he left the locker room. "I had to make sure I called the wife and let her know, `Babe, I'm good. I've got all my senses back.'"

 > As far as other injuries, the Packers also lost No. 2 running back Brandon Jackson to an ankle injury on the first offensive series of the third quarter, but Jackson said after the game that x-rays were negative. McCarthy said Jackson's injury was a "bruised shin."

 "The injury's not that bad. The ankle's just a little bit swollen," said Jackson, who was taken to the locker room on a motorized cart and did not return, although the cart did drive him back onto the field later in the second half. "I'm pretty sure I'll be able to play at Tennessee (on Thursday)."

 In addition to losing Jennings and Jackson, McCarthy said safety Atari Bigby suffered a sprained thumb and defensive end Michael Montgomery suffered a broken hand.

 > While writers on tough newspaper deadlines were bemoaning the crazy ending that saw the Cardinals and Packers combine for 19 points in the final 1:35, McCarthy wasn't amused, either. Although cameras caught him smiling at one point during the craziness -- after the Cardinals' failed 2-point conversion attempt at 38-37 and after Ruvell Martin's 39-yard touchdown return on Arizona's second onside kick -- McCarthy called it a learning experience.

 "We can definitely learn from some of the things that went on at the end of the game. We had a chance to end the game twice and we did not, so I promise you we’ll learn from that as a football team," McCarthy said.

 > Wide receiver Donald Driver said it's hard to imagine a quarterback playing better than Aaron Rodgers is right now, and he's probably right.

 Rodgers completed 14 of 19 passes for 258 yards and three touchdowns -- 3- and 11-yarders to Jermichael Finley and a 76-yarder to Jordy Nelson -- for a 155.2 passer rating in the first half Friday night. Combined with his numbers in the first two games, Rodgers went into the half having completed 27 of 38 passes for 458 yards with six touchdowns and no interceptions for an overall passer rating of 151.1.

 Rodgers has now directed 12 possessions, resulting in nine touchdowns, one field goal, one missed 29-yard field goal, and one series that ended after a fourth-down failure at Buffalo's 15-yard line.

 "I thought we were great tonight," Rodgers said after the game. "Three games, no punts for the first team, 31 points tonight. Again, I'll say it, the line was great, I barely got touched. The run game, I thought we opened some holes up and then it's just pitch and catch out there, and the guys made plays. Jordy was wide open on that one. I was just trying not to overthrow him. Donald made a big play when they jumped offsides, and James (Jones) had a great catch down the sidelines and Jermichael made a great adjustment on two balls, and we just made plays."

 > Martin's night on special teams was ... interesting.

 Forced to hold for kicker Mason Crosby's placekicks with the usual holder, No. 2 quarterback Matt Flynn, sidelined with a shoulder injury, Martin watched Crosby miss from 29 and 48 yards (he also made a 27-yarder).

 Then, on the "hands team" for onside kicks, he saw Cardinals kicker Neil Rackers recover his own onside kick to set up Arizona's last touchdown, which cut the lead to 38-37 before a failed 2-point conversion attempt, then returned the next onside kick for a touchdown -- that he shouldn't have -- with 33 seconds to play.

 "After I scored the touchdown, I'm like, `Shoot, I should've went out of bounds. (Arizona) only had one timeout; two knees, the game's over with,'" Martin explained. "That's a situation we talk about on offense, so I was aware of it, but that's not a situation you talk about it (on an onside kick). If they march down the field and score again, then yeah, I screwed up (by scoring a touchdown). What are the chances they're going to kick it right to me and no one's going to cover me? But, lesson learned."

 As for the holds, Martin said it was his fault on the 29-yard miss.

 "I personally didn't think I hit the spot. You get used to knowing how far just by feel, and I was like, `This doesn't feel right,'" Martin said. "And as soon as Mason hit it, he knew it wasn't right and said something to me. I'm not sure what happened on the second one. I thought everything was fine."
