The Green Bay Packers have signed practice-squad tight end Justin Perillo to the active roster, placed safety Sean Richardson on injured reserve and signed defensive back Kyle Sebetic to the practice squad.

General manager Ted Thompson announced the roster moves on Wednesday.

Perillo, 6-foot-3, 250 pounds, is in his second season out of Maine. Originally signed by the Packers as an undrafted free agent last year, he began the 2014 season on the practice squad but was promoted to the active roster on Nov. 15, where he spent the rest of the campaign and played in two games.
