Delaney was waived by the Dolphins on Wendesday, Joe Schad of The Palm Beach Post reports.
Delaney suited up in two games for the Jaguars in 2018, playing just one defensive snap, before he signed with the Dolphins on a reserve/future contract. The 24-year-old will hope to make a roster out of camp if he receives an invitation.
Delaney had brief stints with the Dolphins and Jaguars in 2018, and was active for two games while in Jacksonville. The undrafted rookie out of Miami (Fla.) is set to spend his first full offseason in the league with the Dolphins.
Delaney was waived by the Dolphins on Saturday.
This motion comes just four days after the Dolphins claimed Delaney off waivers. If the Miami product clears waivers again, he could find his way back to the Dolphins' practice squad. In a corresponding move, the Dolphins promoted fellow cornerback Jalen Davis to the 53-man roster.
The rookie out of Miami appeared in two games for the Jaguars before being waived. Delaney will be tasked with providing depth to Miami's secondary. If Cornell Armstrong (knee) misses Sunday's game against the Patriots, Delaney could be thrust into action behind Bobby McCain.
Delaney was waived by Jacksonville on Monday, John Oehser of the Jaguars' official site reports.
Delaney became the odd man out following Leonard Fournette's return from his one-game suspension. The 23-year-old appeared in just two games for the Jaguars this season.
