It’s been a trying season for Detroit’s star safety. He’s been hampered by two separate knee injuries, the first suffered in training camp, the second in Week 4.

Lions All-Pro safety and noted Vikings villain Kerby Joseph will miss Sunday's game against Minnesota due to a knee injury, Dan Campbell said on Friday. He's getting healthier but isn't ready to make his return to action yet.

ALLEN PARK -- The Detroit Lions were missing two players from Thursday’s practice. But they saw the return of pass rusher Al-Quadin Muhammad (hamstring) back on the field in the good news department.

The Detroit Lions are rumored to be focusing on adding at at least two positions on the defensive side of the ball ahead of the trade deadline and one of them is a surprise.

The availability of Detroit Lions safety Kerby Joseph against the Minnesota Vikings is now up in the air. Dan Campbell's squad returned to the practice field on Thursday afternoon, after the players had a scheduled day of off on Wednesday.

The Detroit Lions are expecting to have offensive tackle Taylor Decker when they take the field for Sunday's home game against the Minnesota Vikings.

Coach Dan Campbell said Friday that Joseph (knee) is not expected to play Sunday against the Vikings, Eric Woodyard of ESPN.com reports.

One of their littlest fans has a suggestion for Sunday’s game. Four-year-old Ace Morris showed Detroit Lions players Jameson Williams and Kerby Joseph his moves at Jaymo’s trunk-or-treat in Detroit. He told FOX 2's Jessica Dupnack that he learned his dances from watching videos and mimicking the moves.
