Joseph Addai "day-to-day"

Colts HC Jim Caldwell labeled RB Joseph Addai (hamstring) "day-to-day."  He didn't practice on Wednesday.  "[He's] improving, but it just depends upon how quickly," Caldwell said.  Those close to the Colts don't expect Addai to play against the Bengals this weekend.  We should have a better idea of his status by Friday.  RBs Delone Carter and Donald Brown are next in line if Addai can't go.
