Bad news, folks. Joseph Addai is going to miss some time.

Colts running back Joseph Addai has a slightly torn hamstring that is expected to sideline him two to four weeks, according to a Colts source, and rookie running back Mike Hart has a torn ACL that landed him on the season-ending injured reserve list, Indianapolis coach Tony Dungy confirmed Wednesday.

Dungy said he envisions using Dominic Rhodes, Dawson and Simpson on Sunday at Green Bay. Dungy also said he does not think Addai’s injury is of the long-term variety, and it wouldn’t surprise Dungy if Addai could be lobbying to play by the end of the week.

But before that happens, Addai also is expected to seek a second opinion on his hamstring injury. As much as he would like to play, he also knows that if he comes back too soon from it, he risks aggravating it and sidelining himself even longer. So the inside word is, look for Addai to miss anywhere from two to four weeks, though it probably will turn out to be less time than more.

Savvy Addai owners should already have Dominic Rhodes on their roster, though sometimes roster limitations make that difficult. Grab him if you can, even if you don’t have Addai. He should be a productive RB2 as long as Addai is out.

Here’s a look at several players that might be available in your league…

Zach Miller was once again the Raiders’ top receiver (3-46) and it seems like he and JaMarcus Russell are starting to develop a rapport…Jeff Garcia (173 yards, TD) is back to being a decent fantasy backup…Devin Hester is averaging 4.7-60-0.7 over the last three games. It will be interesting to see if he can keep this up once (if) Brandon Lloyd returns…Don’t go crazy trying to pick up Patrick Cobbs (3-138-2) this week. This looks more like an aberration than anything else…Greg Camarillo (4-49) continues to post decent numbers in PPR leagues…With Joseph Addai hurt, Dominic Rhodes (25 carries, 73 yards, TD) looked strong. Addai tweaked his hammy, so Rhodes’ value will depend on when Addai can return…Joe Flacco (241 yards, 3 INT) was brutal against the Colts…Donnie Avery (4-73) has caught at least three passes in each of the last three weeks… Just when fantasy owners gave up on Matt Jones (7-69) again, he put up another good game in PPR leagues…Michael Pittman (23 touches, 125 yards) got all of the work with Selvin Young out. Oddly enough, Andre Hall didn’t register a touch…Steve Breaston (8-102-1) continues to shine with Anquan Boldin out.
