Raiders signed TE Jeron Mastrud, formerly of the Dolphins.
Mastrud, 25, appeared in 14 games with Miami last season, playing 100 snaps. He wasn't targeted in the passing game and is purely a blocker. The Raiders also claimed WR Andre Holmes off waivers from the Patriots. To make room, Oakland released TE Mickey Shuler and DB Akwasi Owusu-Ansah.
