With the Packers dealing with quarterback issues, they turned to rookie running back Eddie Lacy to move the ball in Sunday's tie with the Vikings.
And Lacy delivered, rushing for 110 yards and a touchdown on 25 carries and catching six passes for 48 yards. His 158 yards from scrimmage were a career high.
But Lacy missed the Packers' final two drives in overtime after his asthma flared up on the 19-degree day in Green Bay.
"It's worse in the winter time," Lacy said to the Milwaukee Journal Sentinel after the game, which was the first tie between these two teams since 1978 and only the fourth tie in the NFL since 2000. "I've had it since I was little. Sometimes it's worse than others.
"And it's going to get worse, I think."
Lacy, who played high school football in Louisiana and college ball at Alabama, isn't looking forward to two December home games and a trip to Chicago.
Lacy ran only three times for six yards in overtime on Sunday, and with him out of the game, the Packers ran it only twice more, but that was mostly because the clock was winding down.
Lacy has rushed for 806 yards and six touchdowns on 197 carries this season and has 22 catches for 158 yards. He's also proven to be a dependable ball carrier, as his only lost fumble came in the first game of the year.
"The guy's a monster," said nose tackle Ryan Pickett. "I love him. Tough. He's already a leader. He's like a vet already."
