ALLEN PARK -- Kerby Joseph’s injured knee isn’t healing as fast as the Detroit Lions hoped it would.

Let’s pop the hood and do a midseason diagnostic check on the key topics that surrounded this team entering Week 1.

The problems showed in the Lions’ Pro Football Focus grades as Detroit was given a 63.8 overall grade, the team’s second-lowest of the season after their Week 1 loss to the Green Bay Packers.

The Lions, coming off their bye week, own a 5-2 record and sit at second place in the NFC North behind the Green Bay Packers. Meanwhile, the Vikings, losers of two straight, possess a 3-4 mark and sit in last place in the division. They're coming off a 37-10 loss to Justin Herbert and the L.A. Chargers in Week 8.

Detroit will resume its quest for its first Super Bowl appearance after the bye. The Lions will play Minnesota at Ford Field and will also host the New York Giants, Green Bay, Dallas and Pittsburgh with road games remaining against Washington, Philadelphia, the Los Angeles Rams, the Vikings and Chicago.

In what sounds like the worst uniform matchup in recent memory, Aaron Rodgers and the Pittsburgh Steelers (4-2) will host the Green Bay Packers (4-1-1) on Sunday Night Football in Week 8. This will mark the first time Rodgers faces his former team for whom he played for 18 seasons.

The Detroit Lions on Tuesday became the fourth and final team in the NFC North to enter its bye week, getting some time off later in the calendar than the Green Bay Packers (Week 5), Chicago Bears (Week 5) and Minnesota Vikings (Week 6).

The Detroit Lions were stunned by J.J. McCarthy and the Minnesota Vikings in a Week 9 NFC North showdown at Ford Field. Here are the highlights.
