The 49ers claimed linebacker Roderick Green off waivers from Baltimore on Sunday before adding five players from training camp to their practice squad. Green, who played all 16 games as a backup for the Ravens last season, will be reunited with 49ers coach Mike Nolan -- his defensive coordinator during his rookie season in 2004. Green can play both inside and outside in Nolan's schemes. "Physically, he is a gifted guy," Nolan said of Green, who has added 20 pounds of muscle since Nolan left Baltimore. "Very strong, and he has been a good pass rusher. I would like for him to be an every-down player, but we will see what he gives us."
