Harrison (undisclosed) was released by the Lions Thursday and will seek to return to action in 2020 after considering retirement at the end of last season, Tom Pelissero of NFL Network reports.

EDGE Analysis

Harrison signed a one-year, $11 million contract extension with the Lions prior to the beginning of the 2019 campaign, finishing the season with 49 tackles and two sacks in 15 games. He will hit the free-agent market as a veteran player that could make a legitimate impact on a team's interior defensive line, provided he is healthy.

Harrison (undisclosed) has not yet made a decision on his future with the Lions, Kyle Meinke of MLive.com reports.

EDGE Analysis

Harrison said following Detroit's season-ending loss to the Packers that he's considering both retirement and surgery (he dealt with numerous lower-body injuries in 2019) this offseason. It appears as though the 31-year-old, who remains under contract with the Lions through 2021, is sincerely considering the possibility of hanging up the cleats. With no incentive to rush the decision, it could realistically be multiple weeks until Harrison makes up his mind.

Harrison (undisclosed) said after Detroit's season-ending loss to Green Bay that both surgery and retirement are on the table for him this offseason, Carlos Monarrez of the Detroit Free Press reports.

EDGE Analysis

Harrison dealt with a number of lower-body injuries this season, but it's not clear which could be the motivation for why he might go under the knife. Meanwhile, it's tough to gauge how much stock one should put in the 31-year-old's retirement chatter considering it might have been an emotional reaction in the wake of a down year for him. After all, Harrison racked up more tackles (50) in 10 games with Detroit last year than he did in 15 games this year. In the end, it'd be a surprise if Harrison passes up on serving out the final two years of the lucrative extension he signed last summer.

EDGE Analysis

After missing last Thursday's Thanksgiving clash with the Bears, Harrison appears good to go for Week 14 and should be on the field Sunday when Detroit visits Minnesota to face the Vikings at U.S. Bank Stadium.

Harrison (knee) is inactive for Thursday's game against the Bears.

EDGE Analysis

Harrison suffered a knee injury versus the Redskins this past Sunday, and he won't manage to retake the field due in part to a short week of recovery. Mike Daniels and John Atkins stand to play expanded roles on defense in Harrison's stead.

Harrison (knee) is considered questionable for Thursday's game against the Bears.

EDGE Analysis

Harrison overcame a groin injury to play this past Sunday against the Redskins, but he picked up a knee injury in the contest. The 30-year-old defensive tackle was limited in practice all week, and his final status will be revealed 90 minutes before Thursday's 12:30 p.m. ET kickoff.

Harrison (groin) is active for Sunday's game against the Cowboys.

EDGE Analysis

The Lions took cautionary steps with Harrison since he's been battling this groin injury for nearly a month, but the veteran defensive tackle should resume starting reps. Harrison's a valuable run-stopper, and he's marked 28 tackles (17 solo) and two sacks through nine games this year.

Harrison (groin) was a full participant in Wednesday's practice.

EDGE Analysis

Harrison managed to play through a groin injury during Sunday's loss to the Bears, during which he notched four solo tackles, and he now appears to have moved past the issue entirely. Barring any setbacks, expect the veteran defensive tackle to play his usual role during Sunday's tilt against the Cowboys.

Harrison is questionable for Sunday's game against the Bears due to a groin injury.

EDGE Analysis

Harrison suffered the groin injury Week 8 against the Giants but played through the injury in last week's loss to the Raiders. The 30-year-old seems likely to be available for Week 10, but his status will officially remain up in the air until Sunday.

Harrison tallied six tackles (five solo) in Sunday's 31-24 loss to the Raiders.

EDGE Analysis

Harrison shook off a groin injury to suit up for this contest. He logged 28 of 72 defensive snaps (39 percent) -- his second-lowest mark since Week 1 -- and tied his season high in tackles. Harrison will continue stuffing runs against the Bears in Week 10.
