ARLINGTON, Texas — Matt Flynn couldn’t cut it with the Seahawks, Raiders and Bills, but there’s something about the way he plays when he’s in a Packers uniform. He threw four touchdown passes in the second half to lead Green Bay to the largest comeback in franchise history, erasing a 23-point halftime deficit to win in Dallas, 37-36.

Flynn is standing in for Aaron Rodgers, who is recovering from a broken collarbone and has not been cleared to play.

It was just the second time the Cowboys have blown a lead of 23 or more, and the loss has rekindled the Tony Romo-must-go talk, as he had two crucial interceptions with the game on the line. Dallas (7-7) can still win the NFC East by winning its final two games.

“It took me everything not to cry,” said Packers coach Mike McCarthy. “I’m just drained. Just the sheer emotion. It was incredible.”

Jamaal Charles turned the Kansas City Chiefs’ playoff clinching party into a game-long celebration. Charles scored the first of his team record-tying five touchdowns on a 49-yard screen pass on the first play from scrimmage, sending the Chiefs to a 56-31 win over the Oakland Raiders that clinched at least a wild-card spot.

“A big part of this team depends on me, Charles said. “Once I’m healthy, this offense can go a long way and this team can go a long way.”

Brady was intercepted in the end zone on fourth down with two seconds left by Dolphins newcomer Michael Thomas.

“The longest 75 seconds of my life,” Dolphins quarterback Ryan Tannehill said of waiting on the sideline as Brady tried to wield his magic again.
