Anderson (ankle) did not practice Wednesday, ESPN.com reports.
Nor did fellow RB Ronnie Hillman (foot), with coach Gary Kubiak calling Anderson "day-to-day," while adding that he expects Hillman to practice some Thursday. Per Troy Renck of the Denver Post, Anderson "remains hopeful (his) ankle will be fine" for Sunday's game against the Raiders, but in any case, the running back's status is clearly worth tracking in advance of that contest following Wednesday's missed practice session.
