The 49ers and Roderick Green have agreed to a contract, according to Green's agent, and the pass-rushing linebacker is expected to begin practicing with the team this week. Green, 25, had 4.5 sacks last year despite playing just half the season. Yet, when the 49ers moved to a 3-4 defense this summer, he became expendable. The 49ers had hoped that the pass rush would be supplied in large part by free-agent linebacker Tully Banta-Cain. The former New England Patriot, however, has only 1 1/2 sacks over the first half of the season. Green worked out for the team yesterday at which point he agreed to the contract. The 49ers also signed offensive lineman Sean Estrada to the practice squad.
