The 49ers' Aldon Smith insisted Tuesday that his shoulder was not an issue even through he did not have a sack in the final six games, including in the Super Bowl loss to Baltimore.

"I don't think my shoulder was a problem at all," said Smith, who had 19.5 sacks in the team's first 13 games.

Smith said he feels "all right" and that he just needs "rest" in the offseason.

Asked about the 49ers' lack of a pass rush late in the season, Smith added, "We didn't get to the quarterback as much as we should have. But they were blocking us a lot of different ways. The ball was coming out a lot faster."
