Taking a look at significant injury situations as the NFC North practice week begins:
Chicago Bears: Linebacker Lance Briggs (foot) and linebacker Hunter Hillenmeyer (ribs) sat out practice Wednesday. Briggs’ injury is not believed serious, but Hillenmeyer seems likely to be replaced by Nick Roach in the starting lineup. If that occurs, Jamar Williams would be the top candidate to start at strongside linebacker Sunday against Detroit. Opening-day starter Pisa Tinoisamoa (knee) apparently needs at least another week.
Detroit Lions: Defensive end Cliff Avril (hamstring) and linebacker Ernie Sims (shoulder) returned to practice on a limited basis, and you can’t rule out either player yet from playing Sunday at Chicago. But defensive tackle Sammie Lee Hill (ankle), tailback Kevin Smith (shoulder) and defensive end Dewayne White (hamstring) all sat out Wednesday. The Lions’ decision to re-sign defensive tackle Chuck Darby indicates Hill’s injury could be lasting.
Neither Green Bay nor Minnesota held a full practice Wednesday.
