The team has placed tight end A.J. Derby on IR and claimed rookie cornerback Dee Delaney off of waivers from the Jacksonville Jaguars.
Derby, 27, joined the Dolphins in the middle of last year’s campaign after two seasons with the Denver Broncos. Following MarQueis Gray’s season ending injury in training camp, Derby was in line for a key role in the offense alongside rookie draft picks Mike Gesicki and Durham Smythe. Unfortunately for Derby, a foot injury has limited him to just four games this season, during which he caught three receptions for 48 yards and one touchdown.
