Alex Smith has thrown four interceptions with a 55.4 passer rating since injuring his middle finger on his throwing hand on Oct. 14.

Smith and the San Francisco 49ers had extra rest following their Thursday win against the Seahawks.

Jim Harbaugh is seeing a difference in Smith's throwing in practice.

“Yeah, it was a good week throwing the ball, very good this week,” Harbaugh said. “I think he feels very good physically. Confident going into the game and ready to roll.”
