Lions CB Chris Greenwood underwent sports-hernia surgery during the offseason.

Greenwood (6-foot-1, 193) has been sidelined at OTAs. The Lions' official website pegged the 2012 fifth-rounder as a potential breakout candidate last month. Especially after the Lions failed to address the cornerback position for the most part, Greenwood could take on a bigger role. He should be ready for camp.

The Lions' official website believes CB Chris Greenwood "could be a real wild card" and compete for defensive snaps.

Greenwood, a 2012 fifth-rounder who's in his second stint with the Lions after a brief pitstop in Dallas, played 67 snaps -- his only snaps of 2013 -- over the final two games last season and received positive marks from Pro Football Focus. He has ideal size at 6-foot-1 and 193 pounds. The Lions are looking for any help they can get at cornerback after LCB Chris Houston's disastrous 2013.

Lions re-sign exclusive-rights free agent CB Chris Greenwood.

It is a one-year, $570,000 deal for the former fifth-round pick. Greenwood was picked up off waivers by Detroit last October. He recorded six tackles in three games for the Lions in 2013.

Lions waived CB Chris Greenwood.

A fifth-round pick in 2012, Greenwood missed his entire rookie year abdominal injury. It's a bad sign that he can't stick on the final roster of a team desperate for playmakers at corner.

MLive.com doesn't expect Lions CB Chris Greenwood to be in the mix for a starting job this season.

GM Martin Mayhew has called Greenwood a player with "starting potential," but the 2012 fifth-rounder missed his entire rookie season with an abdominal injury. The Lions are sorting through Greenwood, Darius Slay, Bill Bentley, Jonte Green and Ron Bartell opposite Chris Houston. No. 36 pick Slay is likely the Lions' preferred choice.

Lions CB Chris Greenwood expects to compete for a starting job this season.

A fifth-round pick last spring, Greenwood missed his entire rookie year as he recovered from abdominal surgery. DetroitLions.com reported in January there were "some lofty expectations being floated around" for Greenwood. It would be far from ideal for the Lions if they entered Week 1 with Greenwood starting opposite Chris Houston.

DetroitLions.com says there are "some lofty expectations being floated around" the organization for CB Chris Greenwood next season.

Greenwood missed his entire rookie season in 2012 after undergoing abdominal surgery. The fifth-round pick out of D-III Albion has an intriguing blend of size (6-foot-2) and speed (4.42) that had DC Gunther Cunningham comparing him to Brandon Carr after the 2012 draft. The Lions have four corners set to be free agents this offseason, so Greenwood could be in for a big role in 2013.

Lions kept CB Chris Greenwood (abdominal surgery) on reserve/PUP, ending his season.

Greenwood has been practicing for three weeks, but the Lions have deemed him not ready to help in 2012 after missing out on offseason and training camp workouts. The rookie fifth-rounder is an athletic size-speed corner out of small-school Albion.

Lions CB Chris Greenwood (abdominal surgery, PUP) has resumed practicing.

Detroit now has three weeks to activate Greenwood from the PUP list. With the Lions' secondary among the thinnest in the league, it's likely a matter of when, not if, they activate their fifth-round draft pick.

Lions rookie CB Chris Greenwood (abdominal surgery) is expected to open the season on the reserve/PUP list.

Greenwood is a raw fifth-round pick out of Albion College, so the Lions weren't counting on him for much first-year impact anyway. He's been slow to recover from a May surgery. Greenwood could be activated from reserve/PUP by Week 8. He'll be out for the first six games, and the Lions have a Week 5 bye.

Lions rookie CB Chris Greenwood remains sidelined from training camp following May surgery to repair a lower abdominal tear.

Coach Jim Schwartz offered no timetable for return. Greenwood has long-term promise as a long young corner with speed to match up against big, tall wide receivers, but he's not going to make an early impact in Detroit's secondary.

Lions fifth-round CB Chris Greenwood is recovering from surgery to repair a torn lower abdomen muscle.

Greenwood suffered the injury during a May OTAs session, and missed minicamp as a result. He'll begin training camp on the active/PUP list. Greenwood is unsure of when he'll be able to resume practicing. "I'm rehabbing now and running and jogging and hopefully I'll be back sooner rather than later." The injury severely dampens Greenwood's chances of earning a starting job opposite Chris Houston.

Lions fifth-round CB Chris Greenwood (undisclosed) "should" be ready for training camp.

Greenwood wasn't known to be hurt, but apparently "missed a lot of time in the offseason." The Lions traded up to select Greenwood with the No. 148 pick, so his roster spot should be secure. However, missing the beginning of camp would likely leave him as a game-day inactive for at least the first few weeks of the season.
