About two months ago, Nick O’Leary signed on with the Raiders. Today, the team announced that the tight end has been placed on the reserve/retired list. 
O’Leary, 28 in August, split his 2019 season between the Jaguars and Dolphins. After entering the league as a fifth-round pick of the Bills in 2015, he enjoyed a five-year career as a reliable role player and a pass-blocker. Now, he’s moving on to something new.
To replace O’Leary on the roster, the Raiders re-signed free agent Paul Butler. The tight end spend time with the Raiders over the last two years and he’ll return in 2020 to join them in Las Vegas. He also spent time with the Lions as a reserve/future signing, but he has yet to see live regular season action in the NFL.
Butler will fight for his spot on the 53-man roster, competing in camp alongside tight ends Darren Waller, Jason Witten, Foster Moreau, Derek Carrier, and UDFA Nick Bowers.
He was a 6th rounder not a 5th rounder
He played like a 5th rounder…
Just wanted to retire a Raider…
First time I’ve read something about O’Leary and there’s no reference to his famous family lineage
