If you missed it, the Green Bay cornerback ruffled some serious feathers over the weekend when he nearly blew the coin toss for his team just prior to its tilt with the Panthers in Carolina.

Alexander unexpectedly joined the Packers' captains at midfield ... called tails, and when he told the refs he wanted to start the game on defense -- it almost cost the Pack a possession.

Thankfully for Alexander and Green Bay, the snafu got cleared up and the team went on to win 33-30 ... but on Wednesday, the Packers made it clear they're furious over the situation.

General manager Brian Gutekunst said the 26-year-old has been banned one game for the incident ... adding in a statement, "Jaire's actions prior to the game in Carolina led us to take this step."

"As an organization, we have an expectation that everyone puts the team first."

Gutekunst also said the team and Alexander had a conversation about the situation Wednesday morning and the org. "fully" expects him "to learn from this as we move forward together."

Alexander has not publicly commented since the ban was announced -- though in a postgame meeting with reporters Sunday, he didn't show much remorse for his actions ... appearing to say he took it upon himself to go out with the captains since the Packers were playing in his hometown of Charlotte.

Alexander is widely regarded as one of the best young corners in the game -- he's made two Pro Bowls in his six-year career -- although injuries have sidelined him for most of this season.
