It's much more than a sprained ankle for Ryan Grant.  The Packers today put last year's 7th leading NFL rusher on injured reserve with ligament damage in his right ankle that will require surgery.  A pin will need to be implanted to secure the damaged ligament to the bone.   Grant was hurt in the second quarter of Sunday's opener in Philadelphia after an 18 yard gain and his loss will severely hamper Green Bay's offense and possibly their hopes for a playoff run.   Grant rushed for over 1200 yards last season and was a Pro Bowl 2nd alternate.   Backup Brandon Jackson, who has 689 yards in his three plus seasons will become the primary halfback for the rest of the season.  Grant's roster spot was filled by Dimitri Nance, a rookie running back from Arizona State who was on the Atlanta Falcon's practice squad.  An undrafted free agent, Nance (5-10, 219) rushed for 795 yards and 6 touchdowns for the Sun Devils last year.

The Packers also announced they've formally placed Justin Harrell on injured reserve with an ACL tear in his left knee.  Green Bay re-signed Jarius Wynn, the team's 6th round draft choice in 2009 out of Georgia.   He was among the final roster cuts earlier this month.
