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 is recovering from an operation to "help with his sleep apnea."

The operation was disclosed in mid-May, but the nature of it was not. From a football standpoint, it's good news. Now down to 295 pounds, Fairley is getting his ducks in a row as he attempts to go off in a contract year.

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.

Lions DT Nick Fairley is recovering from an undisclosed operation, and not participating in OTAs.

Coach Jim Caldwell would only disclose that Fairley is dealing with a "medical issue." Perhaps he had an appendectomy. The news comes three weeks after the Lions declined to exercise Fairley's fifth-year team option. Issues like this are the precise reason why Fairley is being forced to play out his rookie deal. Frequently injured and out of shape, it's unclear when Fairley will be ready to return.

The Lions will not exercise DT Nick Fairley's fifth-year option for 2015.

It means he'll be an unrestricted free agent next offseason. According to the team's official website, GM Martin Mayhew wants Fairley motivated for 2015, and doesn't believe he's a "$5.5 million player right now." The No. 13 overall pick of the 2011 draft, Fairley has dealt with weight and injury issues. A consistent and healthy 2014 could result in a monster payday.

MLive.com's Kyle Meinke believes Lions DT Nick Fairley's weight had reached "at least" 320 by late last season.

Meinke observed Fairley playing with a "sizable belly." Fairley is listed at 6'3/291 on the Lions' website and measured 6-foot-3 7/8, 291 at the 2011 Combine. GM Martin Mayhew recently reiterated he wants Fairley's work ethic to improve. "I'd like to see his commitment to the offseason program improve, and see him on a consistent basis," said Mayhew. "It's voluntary, but if he's not training with us, I'd like to see him training somewhere."

Lions GM Martin Mayhew says DT Nick Fairley could stand to "reposition" some weight.

Fairley is listed at 6-foot-3, 291 on the team's official website. The number is fine, but Fairley's belly was noticeably larger than it was just a couple years ago at Auburn. He still had a heck of a 2013 season, starting a career-high 15 games and posting new career-bests in tackles (35) and sacks (6). Fairley has one year left on his rookie deal, though the Lions hold a 2015 option.

Lions DT Nick Fairley finished his third NFL season with career highs in tackles (35), sacks (6.0), and starts (15), also registering two forced fumbles.

Turning 26 later this month, Fairley turned in a true breakout campaign, finishing No. 15 overall in Pro Football Focus' defensive tackle pass-rush ratings. Teammate Ndamukong Suh was No. 2. Fairley needs to cut down on his penalties -- he was flagged 13 times in 2013 -- but he's already a star. The Lions' defensive line remains the team's primary strength entering the offseason.
