Muhammad Wilkerson undergoes ankle surgery

Green Bay defensive lineman Muhammad Wilkerson underwent surgery Sunday night after suffering a "significant" injury to his left ankle in the loss to the Redskins, Packers coach Mike McCarthy confirmed Monday.

Wilkerson left the field on a cart in obvious pain during the second quarter of Green Bay's 31-17 defeat. He was taken from FedEx Field to a Washington-area hospital, where he remained overnight.

"There was a procedure he needed before he could travel," McCarthy said. "I would say it's significant."

The NFL Network's Ian Rapoport reported Monday that the injury is likely season-ending.

Wilkerson, 28, is in his first season with the Packers. He played the previous seven seasons with the New York Jets, earning a Pro Bowl selection in 2015 with a career-high 12 sacks.

A 2011 first-round draft pick from Temple, Wilkerson signed a one-year, $5 million contract with Green Bay last March.
