Kerby Joseph: Everything you need to know

The Lions placed Joseph (knee) on injured reserve Saturday. Joseph will miss the remainder of the regular season due to his knee injury, but he could be a candidate to return to action during the playoffs, if Detroit progresses to the postseason. Thomas Harper is set to handle a starting role at free safety versus the Steelers on Sunday, and for the remainder of the regular season, with Joseph sidelined.

Joseph (knee) has been ruled out ahead of Sunday's game against the Steelers. Joseph's knee injury is severe enough that the safety was an IR candidate last week. Since then, it seems the safety has been able to progress enough that he will be able to stay on the active roster, though he will be missing consecutive games. With the starter ruled out, Thomas Harper is in line to play significant snaps at free safety in Sunday's contest.

Lions head coach Dan Campbell said Friday that Joseph (knee) is a possible injured reserve candidate, Tim Twentyman of the Lions' official site reports. Joseph appeared as a limited participant in practice Wednesday, but appeared to have suffered a setback after no participation Thursday or Friday. It looks as though the 25-year-old is set to miss an extended period of time, and it's currently unknown when he will return this season. Thomas Harper will remain as the team's starting safety in Kerby's absence.
