The San Francisco 49ers will acquire Jonathan Martin via trade with the Miami Dolphins.

The Dolphins will acquire a 2015 seventh round pick in 2015 if he remains on the 49ers' opening 53-man roster.

Martin played for Jim Harbaugh at Stanford.

The 49ers like to use a lot of sets features six offensive linemen.

Martin left the Dolphins in late October following a bullying incident involving Richie Incognito.
