Iloka signed a one-year deal with the Cowboys on Saturday, Todd Archer of ESPN.com reports.
The 28-year-old has plenty of experience as a five-year starter with the Bengals, but Iloka started just three games with the Vikings in 2018. Archer added Iloka can play both safety positions, and the Cowboys plan to have him replace Jeff Heath as the starting strong safety while keeping Xavier Woods as the free safety.
