It's too early to worry about his availability for the Philly tilt, but Detroit -- clinging to a one-game lead in the NFC North -- isn't the same without Bush.
Other injuries we're tracking on this fine Thursday:
- Cleveland Browns coach Rob Chudzinski told reporters Thursday that quarterback Jason Campbell has been cleared to return to practice ahead of Sunday's clash with the New England Patriots. Campbell has been held out of team activities since sustaining a concussion in a Week 12 loss to the Pittsburgh Steelers.
- New York Jets coach Rex Ryan told reporters that wide receiver Jeremy Kerley looked "outstanding" in practice and is expected to play Sunday against the Oakland Raiders. Kerley has missed the past three games -- all Jets losses -- with a dislocated elbow. Santonio Holmes (hamstring) also is expected to play.
- Denver Broncos tight end Julius Thomas (knee) and cornerback Dominique Rodgers-Cromartie (shoulder) were full participants, while wide receiver Demaryius Thomas (shoulder) was limited and return man Trindon Holliday (shoulder) did not practice, The Denver Post reported. Both Thomases are expected to play Sunday against the Tennessee Titans, defensive end Derek Wolfe (illness) is likely out for the game and Holliday is questionable.
