Fairley has not practiced for the past two days as he nurses a knee injury he sustained in the Lions’ 22-21 win over the Atlanta Falcons at Wembley Stadium in London on Oct. 26.
ESPN Chicago's Michael C. Wright reported last week that Fairley's injury is to the MCL and PCL and that he is expected to be out for four or five weeks. That timeline would put his return some time in December. Caldwell said last week that team had no timetable for his return.
Fairley, the 13th overall pick from Auburn in 2011, has 14 tackles and a sack, along with a forced fumble, this season for the Lions.
In 46 career games, Fairley has 13.5 sacks. He scored a touchdown on a fumble recovery last season.
