Williams, 23, originally signed on with the Dolphins as an undrafted free agent out of Tennessee in 2015. He was on and off the Miami’s practice squad before being cut loose coming out of the preseason.
In 2015, Williams appeared in one game for Miami but did not record any statistics.
Slater, 23, is an undrafted free agent out of San Diego State that signed with the Jaguars back in May. Jacksonville, unfortunately, decided to waive him as they trimmed their roster down to the 53-man limit.
He has worked out for the Panthers and Eagles, but was not signed to a contract by either team.
