Injuries: Marvin Jones (knee) not practicing Thursday

Marvin Jones Jr. did not practice for the second straight day this week while dealing with a bone bruise in his knee.

His status for Sunday will be determined on Friday, but missing two practices to start the week isn’t a positive sign for the Lions’ wideout.

After the trade of Golden Tate to Philadelphia, if Jones can’t go Sunday versus the Carolina Panthers, it would make a once-strong unit a concern for Detroit.

If Jones sits, Matthew Stafford’s top two wide receiver targets would be second-year standout Kenny Golladay, and T.J. Jones, who has six total catches on the season.

Tight end Michael Roberts and defensive tackle A’Shawn Robinson also sat out practice on Thursday for Detroit.
