It appears as though the Packers have been bitten by the “Stalter Curse,” as FOX Sports.com’s Jay Glazer is reporting that running back Ryan Grant is done for the season with severe ankle and leg injuries.

I picked the Packers to win the Super Bowl this year in my 2010 NFL Season Preview last week. My partner in crime John Paulsen knew bad news would eventually be coming to his Packers soon thereafter and here it is, right on time.

Grant is expected to be placed on IR, which would leave the Pack with Brandon Jackson as the starter and John Kuhn as the backup. Jackson rushed 18 times for 63 yards in relief of Grant in last weekend’s win over the Eagles. His 3.5 YPC average doesn’t look impressive on paper, but keep in mind that Green Bay was protecting a lead at that point and Philadelphia was loading the box in efforts to stop the run.

Expect the Packers to add a free agent at some point soon. Willie Parker is available after the Redskins released him last week, although he proved this offseason that he doesn’t have much left in the tank at 30. I would expect Green Bay to snatch a back off of some team’s practice squad before signing Parker, but you never know. Keep an eye on players like Ryan Torain, Chris Henry, Ian Johnson, Chauncey Washington and Brandon Minor.

What a blow for the Packers.

Obviously, if you were planning to go after Brandon Jackson before, you really need to go after him now. He’s fantasy RB2-caliber the rest of the way, especially in PPR leagues, since he’s so adept in the passing game. He’s not the inside runner that Grant is, so John Kuhn is likely to get the goal line work until the Packers find someone else to sign. In a blind bidding situation, don’t be afraid to put the whole lot down on Jackson. It’s not often that a pretty surefire Top 20 back is up for grabs at this point in the season.
