If you were not making a claim for Packers backup running back Brandon Jackson this week, you may want to make a change to that immediately.

According to several reports, Ryan Grant is done for the season after injuring his ankle last weekend against the Eagles. Grant was seen in a walking boot on the sideline after the injury.

It is believed the Packers will place Grant on season-ending injured reserve.

The other name to know on this roster is fullback extraordinaire John Kuhn, who scored a short-yardage touchdown in Philadelphia on Sunday. He will catch passes out of the backfield too. In deep leagues, he may be worth a flier if you are short on running backs.

Expect the Packers to sign a free agent running back soon to replace Grant on the roster, but this is Jackson's job to lose. The first waiver wire hero candidate of the season has emerged.
