No guaranteed money for Okoye, Williams

IRVING, Texas -- The Dallas Cowboys are not sure when Amobi Okoye will be cleared to return to the football field from what has been called a personal medical issue that kept him out of the game in 2013, but they have bought themselves some time and insurance.

Okoye signed a two-year deal with the Cowboys last week that did not contain any signing bonus or guaranteed money. Okoye, who hopes a reunion with defensive coordinator Rod Marinelli will rejuvenate his career, will make $730,000 in 2014 and $870,000 in 2015.

Running back Ryan Williams signed a one-year deal with no signing bonus or guaranteed money worth $570,000.

The Cowboys have signed five players as free agents so far without signing bonuses: Okoye, Williams, Brandon Weeden, Caleb Hanie and Anthony Spencer.

Spencer has $250,000 of his $1.25 million base salary guaranteed provided he does not reinjure his knee. Jeremy Mincey received the largest guarantee among the Cowboys' free-agent additions at $2 million. Henry Melton received a $1 million signing bonus and would be guaranteed another $9 million in 2015 if the Cowboys pick up his three-year option. Terrell McClain received a $300,000 signing bonus.
