Allen Park, MI (SportsNetwork.com) - Detroit Lions star wide receiver Calvin Johnson returned to practice Friday, though the team has still deemed the All- Pro questionable for this weekend's game at Green Bay.

Johnson sat out both Wednesday and Thursday's sessions with knee soreness before participating Friday on a limited basis. The three-time Pro Bowl honoree, who has totaled 313 yards and four touchdowns on 21 catches through the first four games, hasn't missed a game since the 2010 finale.

The Lions did sign former Buccaneers wideout Kevin Ogletree on Wednesday, though the club was in need of additional depth at the position with veteran Nate Burleson still sidelined with a fractured forearm.

Fellow wide receiver Patrick Edwards is probable for Sunday's key NFC North clash after missing Detroit's last two games with a sprained ankle. The first- year pro was a full participant in practice during the week.

The Lions also enter Sunday's matchup with some uncertainty in the secondary, with cornerback Chris Houston (hamstring) and safety Glover Quin (ankle) also listed as questionable. Houston did get in a limited practice on Friday, however, after missing the previous two days.
