Iupati, who turns 28 years old in May, was drafted by San Francisco with the 17th overall pick in the 2010 NFL draft.
He started as a rookie, playing all 16 games for the first three years of his pro career.
However, Iupati has suffered some dings over the past two years, missing a total of five starts and having to leave games at times.
Iupati is coming off three consecutive Pro Bowls and was a first-team All-Pro in 2012.
