Jon Gruden's Raiders have made some big personnel moves, adding 29 - year - old running back Doug Martin and signing 32 - year - old
wideout Jordy Nelson while releasing 30 - year - old Michael Crabtree.
In the opening days of free agency, they signed longtime Green Bay Packers
wideout Jordy Nelson to a two - year, $ 15 million contract.
They will, however, likely be without
wideout Jordy Nelson, who re-tweaked a previous hamstring injury.
