The 29-year-old Young, who left the game in the second half on a cart, will have surgery. He leads the Bears with a career-high 10.0 sacks this season after recording a total of 6.0 in his first four seasons.
After the game, Young did not want to discuss the injury with the media.
“If it’s on my left side of my body, don’t ask about it,” he said. “… (The right side of my body) feels like a million bucks.”
Young signed a three-year, $9 million contract with the Lions after spending the first four years of his career with the Detroit Lions.
Young has been a bright spot for a Chicago defense that ranks No. 30 in yards allowed and No. 32 in points allowed this season. Stephen Paea is second on the team with 6.0 sacks, while Jared Allen and Jay Ratliff each have 5.5. Allen's 5.5 sacks are a career-low.
The Bears dropped to 5-10 with the loss to the Lions. They close the regular season at the Minnesota Vikings on Sunday.
