The Bills filled the vacant spot on their eight-man practice squad Tuesday, signing free agent DT Rashaad Duncan.
Duncan (6'2" 315) was an undrafted rookie free agent signing of the Tampa Bay Buccaneers last May. He did not make the 53-man roster, but was signed to the club's practice squad to start the season. He also has spent time on the Carolina Panthers practice squad.
Built low to the ground, Duncan was a three-year starter in college at Pitt.
He fills the practice squad spot left by DL Corey Mace, who was promoted to the 53-man roster last week.
