Seth Roberts’ rise from the practice squad gained momentum Tuesday, as the Raiders cut four other receivers, including former Patriot Kenbrell Thompkins.
Thompkins, who had 15 catches for Oakland last season, had been lining up on most of the first-team, three-receiver sets in training camp. But he didn’t make any plays in the first three preseason games and was let go along with Josh Harper, Milton Williams III and returner Trindon Holliday.
Roberts, a year removed from West Alabama, has eight catches for a team-high 133 yards this preseason. With Andre Holmes out with a hand injury, Roberts could be one of five receivers to make the roster, along with Michael Crabtree, Amari Cooper, Rod Streater and Brice Butler.
