Detroit is fifth in points scored in the NFL, fourth in throwing the football, ninth in average gain per pass and first in punt returns on the strength of two long returns for touchdowns by Jamal Agnew.
Shaheen suffered the injury during Sunday's win over the Bengals in Cincinnati, according to coach John Fox. Chicago has just 33 yards of total offense so far. Rookie Tarik Cohen added a season-high 80 yards rushing.
"He takes it very seriously that people expect to see No. 9 out there when the Detroit Lions play", offensive tackle Taylor Decker said.
NO KICK: The Bears have made a league-worst 70 percent of their field goals, and are using a third kicker, Mike Nugent, this season. Abdullah missed two weeks with a neck injury, although there were reports he was out last week more for performance-related reasons than his health. The Lions' defense ranks 27th overall but it has proved it can be opportunistic against bad teams. The Bears announced defensive end Pernell McPhee is doubtful to return to the game with a shoulder injury, and Lions cornerback Darius Slay is being evaluated for a concussion, per team insider Tim Twentyman. Amos (hamstring) and Goldman (hip) were limited in Thursday's practice and are questionable to play at Detroit.
