As for whether calls like the one on Matthews, with less than two minutes remaining in the game, should be subject to replay review, McCarthy isn't necessarily opposed to the idea.

"I think anytime a play can change a game, and that kind of covers a lot of area, with instant replay, that's a constant discussion," he said. "I wish instant replay would be used when we think it's going to be used."

In that vein, McCarthy was referring to the fourth-quarter pass to the end zone for Davante Adams that was close to a touchdown reception, with Kendricks dislodging the ball at the last second. The Packers were waiting for the play to go to review, but it didn't, and they ended up taking a delay of game, losing five yards.

All that said, the call McCarthy was most frustrated about in the game actually occurred in the third quarter, when left guard Lane Taylor was flagged for holding, wiping out a third-down TD pass to tight end Jimmy Graham that would have put the Packers up by three scores.

"When you've got a team on the ropes there, that was the time to get the ball in the end zone," McCarthy said. "The call on Lane was tough. It's a T-E (tackle-end) stunt, and the tackle goes to the ground. But that's football.

"The lesson learned is we have to convert there. Get on to the next series of downs, get down there and score again. That's really what you have to focus on from a coaching perspective.

"There's always going to be those plays that can go either way. As a coach, you can't really worry about that. You can't sit there and count on a call to win a game."

As the offense's missed opportunities piled up, McCarthy said defensively the Packers "didn't handle cornerback Kevin King's injury very well," allowing too many explosive plays in Minnesota's comeback.

King's groin injury will be updated later in the week, as will Rodgers' knee injury, which he played through with more mobility than in the second half of Week 1's victory over the Bears.

McCarthy said Rodgers is understandably sore, but he doesn't know how things compare to a week ago coming off the initial injury. Also, McCarthy expects running back Aaron Jones to be activated to the 53-man roster this week following his two-game suspension.

Coming off a 70-minute overtime marathon in 80-degree heat on Sunday, the Packers are headed to Washington, D.C., in Week 3. Getting physically recovered and ready for another potential weather-related challenge.
