Ryan Grant ran for 1,253 yards for the Packers last year, but his season total in 2010 will be just 45. Green Bay will try to replace Grant's presence in the backfield with Brandon Jackson, a guy with just 689 yards in his career.

He won't be alone though, as the Packers have signed undrafted rookie Dimitri Nance off Atlanta's practice squad, according to The Arizona Republic.

Nance, 22, is coming off a senior season at Arizona State University, during which he rushed for 795 yards and six touchdowns. In his four-year career at ASU, he averaged 4.0 yards per rush while scoring 19 touchdowns.
