Fairly (knee) has been diagnosed with a sprained MCL/PCL and is expected to miss 4-5 weeks, ESPN reports.

Fairly left Sunday's game against the Falcons with the knee injury, and Monday's MRI revealed the damage. Obviously losing Fairley is a tough blow for Detroit, but if all goes well, he should be back in the fold for the final few weeks of the regular season. Fairley has 14 tackles, one sack and one forced fumble this season.

Fairley (biceps) is active for Sunday's game against the Packers.

Fairley came into Sunday's game with a questionable tag after making only limited appearances in practice this week, but he'll presumably be in line for his usual nose duties next to Ndamukong Suh. With Ziggy Ansah (knee) also cleared to play Sunday, the Lions' defensive line could feast on Packers quarterback Aaron Rodgers, who has already been sacked seven times through two games.

Fairley's play has improved since his demotion to second-string, th eDetroit Free Press reports.

Fairley's effort and weight management have been called into question by Detroit, and the demotion could help serve as a big wakeup call for the talented, but not super-productive tackle. C.J. Mosley is in the top spot now, but Fairley could regain the job.

Lions DT Nick Fairley reported to training camp at 305 pounds, down 15 from this time last year.

He's up ten pounds from his minicamp weight, although that appears to be by design. It's worth noting Fairley's 2011 Scouting Combine weigh-in was 6-foot-4, 291. Still only 26, Fairley is entering the final year of his rookie deal. He's collected 12.5 sacks and three forced fumbles through three seasons.

Lions DT Nick Fairley slimmed down to 295 pounds this offseason.

That is 27 lighter than he finished last season. The Lions chose not to exercise Fairley's fifth-year option this offseason partially because of his weight issues and partially to send a message to the young defensive lineman. It seems the message got through. Fairley is currently recovering for an undisclosed operation. If he gets healthy, he could be primed for a huge, contract-year season.
