Fairley, 26, has not played since injuring a pair of ligaments in his knee in Week 8. Meinke reports that Fairley wore a knee brace and appeared to be moving well during Thursday's practice.
In eight games this season, Fairley had 14 tackles, one sack and one forced fumble. He will be a free agent after the season.
Lions defensive tackle Ndamukong Suh had his one-game suspension for stepping on Packers quarterback Aaron Rodgers overturned earlier this week. Suh reportedly claimed his foot was numb and he couldn't differentiate between the ground and Rodgers' leg.
The Lions (11-5) play at the Cowboys (12-4) on Sunday at 4:40 p.m. ET.
