The Cardinals are reportedly visiting with one of the top remaining unsigned offensive tackles.
A 10th-year pro, the 32-year-old Clabo made 15 starts at right tackle for the Dolphins in 2013 after nine seasons with Atlanta (2004-2012).
If signed, Clabo would likely compete to start at right tackle. Eric Winston, who started 16 games on the right side for Arizona in 2013, remains an unrestricted free agent.
The Cardinals begin three days of mandatory minicamp practices on Tuesday.
