ALLEN PARK, Mich. -- The Detroit Lions will be without their best pass-rusher when they face Aaron Rodgers and the Green Bay Packers on Sunday.

The Lions officially ruled out defensive end Ezekiel Ansah with an ankle injury Friday after he missed every practice this week. He wasn't even seen watching on the practice field, something players who are close to returning typically do.

Ansah injured the ankle during the first series of Detroit's 16-15 loss to Tennessee on Sunday. He went back to the locker room soon after the injury and did not reappear on the sideline. He was spotted in the elevator after Sunday's loss but declined to comment on his ankle injury before walking out with a slight limp.

Lions coach Jim Caldwell declined to give any updates on Ansah throughout the week and would not say whether Ansah has a long-term injury. ESPN Insider Adam Caplan reported Thursday night that Ansah would be seeking a second opinion on his ankle.

With Ansah out, the Lions are expected to turn to Devin Taylor and perhaps Kerry Hyder as the team's starting defensive ends. Detroit rotates its ends frequently, so Wallace Gilberry, Brandon Copeland and potentially Anthony Zettel could all see some work there against the Packers.

"We have guys that we have confidence in," Lions defensive coordinator Teryl Austin said. "Obviously, none of them are Ziggy. We know that.

"But we like to think we'll have some strength in numbers. Guys will rotate through and play hard if he's not able to be out there with us."

The Lions are also likely to be without linebacker DeAndre Levy for the second straight week. Levy, who is listed as doubtful, has missed every practice the past two weeks with a quad injury after playing every snap in the season opener against Indianapolis. Levy missed all but one half of a game in the 2015 season with a hip injury.
