The Lions designated Lucas (hamstring) to return from injured reserve Wednesday, Colton Pouncy of The Athletic reports.
Lucas, who's missed each of Detroit's last four contests while on injured reserve due to a hamstring issue, had his 21-day elevation window opened following his return to Wednesday's practice. Unless both the Lions and Seahawks win their respective matchups this weekend, the Week 18 contest versus Green Bay would be the rookie's last chance to suit up this year.
