Harper (concussion) has been ruled out ahead of Sunday's game against the Bears.
EDGE Analysis
Harper upgraded to a limited participant in Thursday's practice but will be unable to make the jump to full participation and clear the league's concussion protocol in time for Sunday's divisional showdown. With Jalen Mills likely set to start at free safety for the Lions in Sunday's contest, Harper ends the season with 37 tackles (26 solo) and five passes defensed, including one interception, over 12 games.

Harper (concussion) was a limited participant at practice Thursday.
EDGE Analysis
Harper was able to make his return to practice for the first time since suffering a concussion Christmas Day against the Vikings. The safety will still have to clear concussion protocol in order to play Sunday against the Bears, but his participation Thursday was a step in the right direction.

Harper (concussion) didn't participate in practice Wednesday.
EDGE Analysis
Harper was diagnosed with a concussion during last Thursday's Christmas Day game against the Vikings. He'll need to clear the NFL's five-step concussion protocol to have a chance of suiting up Sunday versus Chicago. If Harper can't play, Jalen Mills could absorb most of his defensive snaps.

Harper (head) is being evaluated for a concussion during Thursday's matchup against the Vikings.
EDGE Analysis
Harper won't be able to return to action Thursday if he's officially placed in the NFL's concussion protocol. Jalen Mills and Daniel Thomas will both be candidates to handle expanded roles on defense if Harper is not cleared to retake the field Christmas Day.

Harper (concussion) doesn't carry an injury designation ahead of Sunday's game against the Steelers.
EDGE Analysis
Harper was a full participant in practice this week and has officially cleared concussion protocol. The free safety has avoided an injury designation just in time to take up the mantle of starting free safety from an injured Kerby Joseph (knee). Harper's last starting opportunity was in Week 13 against the Packers, when he totaled four tackles (one solo) through 58 defensive snaps.

Harper (concussion) was a Richard Silva of The Detroit News in Wednesday's practice.
EDGE Analysis
It's unclear if Harper remains in the league's concussion protocol, but it appears he has a good chance to suit up Sunday against the Steelers after missing last Sunday's loss to the Rams. With Brian Branch (Achilles) out and Kerby Joseph dealing with a knee injury, Harper could be in line for heavy snaps on defense against Pittsburgh.

Harper (concussion) has been ruled out for Sunday's game versus the Rams.
EDGE Analysis
Harper sustained a concussion during the Week 14 win over the Cowboys on Thursday Night Football. The 25-year-old was limited throughout this week of practice and deemed questionable on Friday, but he'll ultimately miss at least one more game with this issue. With fellow safeties Brian Branch (Achilles) and Kerby Joseph (knee) both ruled out as well, veterans Daniel Thomas, Avonte Maddox and Jalen Mills will all likely take on bigger roles versus LA.

EDGE Analysis
Harper was a limited participant in all three practices heading into Week 15. The 25-year-old suffered a concussion in the Lions' Week 14 win over Dallas and will need to clear the league's five-step concussion protocol before having a chance to play Sunday against the Rams.

Harper (concussion) logged a limited practice Wednesday.
EDGE Analysis
Harper suffered a concussion in Detroit's Week 14 win over Dallas, so it's no surprise that he was limited to begin the week. He'll have to work through concussion protocol before being cleared to play Sunday against the Rams, which will likely require at least one full practice session.
