Jonathan Martin is officially a member of the San Francisco 49ers.

Martin passed his physical Thursday to complete a trade that sent the offensive tackle from the Miami Dolphins to the Niners to be reunited with his college coach, Jim Harbaugh. The teams first announced the move Tuesday night for Martin, who left the Dolphins last fall after accusing teammate Richie Incognito of bullying in a scandal that overshadowed the franchise's 8-8 season.

An investigation for the NFL determined last month that Incognito and two other offensive linemen engaged in persistent harassment of Martin, another offensive lineman and an assistant trainer. After Martin's departure from the Dolphins in late October, he underwent counseling for emotional issues. Incognito was suspended for the final eight games.
