Reese, 6-foot-7 and 325 pounds, is a tackle who played for Mississippi State in college.
The Cardinals seem to have found a potential long-term tackle in rookie Jayden Williams, who is playing the left side after Paris Johnson Jr. suffered a season-ending injury. Veteran Elijah Wilkinson is manning right tackle.
Veteran Jedrick Wills, just signed, missed practice on Wednesday with an illness. The other top reserve tackle is second-year man Josh Fryar.
