Iupati plans to sign with the Arizona Cardinals, NFL Media's Albert Breer reported Monday, per a source involved in the negotiations.
Although merely average in pass protection, Iupati has been one of the NFL's premier run blockers throughout his five-year career.
An offensive line that was among the league's most ineffective in 2012 and 2013 now has the makings of an intriguing group if Jonathan Cooper pans out. General manager Steve Keim recently stated the team still has "huge expectations" after the 2013 first-round draft pick began showing his "natural bend, his athleticism, his speed" late in the 2014 season.
The addition of Iupati is another sign that Keim and coach Bruce Arians plan to overhaul the rushing attack this offseason.
