Second-year defensive lineman Brandon Dorlus earned the second-highest grade in Friday's opener with an impressive 92.2. Wide receiver Chris Blair was the highest-graded offensive player (91.3 overall), while linebacker Josh Woods was the fourth player with an elite PFF grade (91.4).

As always, we’ll take a look at the five highest and five lowest grades on both sides of the football as well as the top five players overall and the five best units. The grades from Pro Football Focus are in after the Lions ’ 17-10 preseason win over the Atlanta Falcons.

But on the Falcons' final drive of the game, Lions cornerback Morice Norris went down with a scary injury that led to him leaving the stadium in an ambulance. NFL Network's Ian Rapoport later confirmed Norris had suffered head and neck injury.

On Friday, Aug. 8, Lions player Morice Norris Jr. was attempting to tackle Falcons running back Nathan Carter when he suffered injuries to the head and neck area. At the time, the Lions were leading 17-10 at the Mercedes-Benz Stadium in Atlanta, the NFL and Sky Sports reported.

Detroit Lions safety Morice Norris posted on social media Saturday that he is “all good” after suffering a scary head injury during Friday night’s NFL preseason game against the Atlanta Falcons that led to the contest being suspended in the fourth quarter.
