Minnesota Vikings quarterback Kirk Cousins suffered a torn Achilles, the team confirmed Monday, which will almost assuredly end his season.

Cousins exited Sunday's game against the Green Bay Packers early in the fourth quarter, and Vikings officials reported after the game that they feared he had suffered a torn Achilles.

Cousins was looking to throw on a third-and-19 play when he went down for a 4-yard loss. He limped off the field as the Vikings field goal unit came out onto the field.

"We're going to have to be there for Kirk every step of the way. And vice versa," O'Connell said, adding he's confident "that Kirk will continue to be the leader of our football team" even if he isn't playing.

Cousins completed 23 of his 31 passes on the day for 274 yards and two touchdowns before giving way to rookie Jaren Hall. The fifth-round pick out of BYU completed 3 of 4 passes for 23 yards and helped finish off a 24-10 victory over the Packers.

Minnesota could also look to the free-agent market for options, such as Colt McCoy.
