Aldon Smith could receive a reduced suspension for good behavior.

Smith was suspended by the NFL for nine games before the season started under terms of the league's personal conduct and substance abuse policies. The San Francisco 49ers could get Smith back one or two games earlier.

Smith must maintain his good behavior for commissioner Roger Goodell to reduce the penalty.

Under terms of his suspension, the league has allowed Smith to be in the team's facility for meetings and conditioning, although he has not been allowed to practice with the team.

A reduction to Smith's suspension would not set a precedent, as other players, including Ben Roethlisberger and Brandon Marshall, have had similar suspensions reduced.
