Jackson (foot) was spotted participating in minicamp Wednesday, Michael Clemons of the Raiders' official site reports.
Jackson was sidelined for Las Vegas' final 13 games last season due to a foot injury, but it now appears he's moved past the issue. The third-year pro from Washington State has primarily contributed as a special teamer throughout his NFL career, recording six total tackles and one pass defensed across 10 contests while logging 148 total snaps (103 on special teams, 45 on defense).
