Fine vindicates 49ers' rookie Anthony Davis

San Francisco 49ers tackle Anthony Davis drew a 15-yard penalty for going after Kansas City Chiefs defensive lineman Shaun Smith in Week 3.

Davis later accused Smith of touching him inappropriately, not the first such allegation against Smith.

The league has levied a $10,000 fine against Smith, but no fine against Davis -- an indication Smith clearly was the guilty party in this incident.
