WR James Jones could miss several weeks with a knee injury.  He caught 7 passes for 68 yards (9.7 avg) with a TD grab this preseason as he was looking to be the #3 WR for the Packers again in 2008.  Jones had a fine rookie season in 2007 with the Packers as he played in 16 games (9 starts) and he caught 47 passes for 676 yards (14.4 avg) with 2 TD grabs.  Look for Ruvell Martin and rookie Jordy Nelson to move up the depth chart until Jones is ready to return.  Martin has caught 4 passes for 51 yards (12.8 avg) this preseason for the Packers.  He played well for the Packers when given the chance in 2007 as he played in 15 games (5 starts) last year for them and he caught 16 passes for 242 yards (15.1 avg) with 4 TD grabs.  Rookie WR Jordy Nelson has caught 5 passes for 48 yards (9.6 avg) this preseason for the Packers and he appears to have a much bigger upside than Martin does.
