Bears place Young on IR, sign Lane
Young, who had a career-high 10 sacks in his first season with the Bears, was injured in Sunday's loss to Detroit.
Lane has appeared in 30 games with 17 starts over four seasons with Jacksonville (2010-12) and Detroit (2013), collecting 64 tackles and three sacks. He signed with the Bears in the offseason but was released at the end of the preseason.
The Bears announced the moves on Tuesday. Chicago (5-10) finishes the season at Minnesota this week.
