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.

Harper (concussion) is questionable for Sunday's matchup against the Rams, Eric Woodyard of ESPN.com reports.
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.

Harper (head) is being evaluated for a concussion in Thursday's contest against the Cowboys.
EDGE Analysis
Harper took a blow to the head while tackling George Pickens in the first quarter, ultimately heading directly to the locker room afterwards. The safety's status for the rest of the game is now up in the air, and in his absence, Daniel Thomas stands to step into a more prominent role in Detroit's secondary.

Harper tallied six total tackles (five solo) and two passes defensed, including one interception, in Sunday's 34-27 overtime win over the Giants.
EDGE Analysis
The second-year pro from Notre Dame made an impact while starting in place of the injured Kerby Joseph (knee) in Week 12, picking off Jameis Winston in the fourth quarter. Harper has now started five games in a row for the Lions, recording 22 total tackles and three passes defensed, including an interception, during that span. He could remain the starter at free safety if Joseph is unable to return for the Week 13 matchup against the Packers on Thursday.
