The second-year player needed stitches to close a cut over his eye after a single car crash in the east San Jose foothills Friday night.
According to a CHP report, Smith was a passenger in the car that swerved to avoid a deer and slammed into a tree. The driver suffered a broken back. Neither drugs or alcohol were involved, and Smith played in the Niners' game on Sunday.
Smith has been involved in two other incidents this year. In June he was stabbed at his home while allegedly trying to break up a fight where two others were shot. He was arrested for drunken driving in Florida in January. The charge was reduced to reckless driving.
