The Saints’ contracts for linebacker Jayrone Elliott and wide receiver Josh Huff were disapproved by the league, according to the league’s transactions wire. It’s not immediately clear why the deals were voided, but Herbie Teope of the Times-Picayne (Twitter link) notes that the Saints were at the 90-man roster maximum before agreeing to deals with both players. It’s possible that the Saints just have to make a pair of roster moves before bringing both players back. 
The Saints plan on bringing Huff back, Teope hears (on Twitter), but we have no word on Elliott one way or another just yet. The pair signed futures deals with New Orleans last week but are now considered free agents.
The Saints now must address their roster issue and refile with the league if it intends to bring one or both players back.
Huff entered the league in 2014 as a third-round pick with the Eagles. He has tallied 51 catches for 523 yards and four touchdowns. Signed by the Buccaneers down the stretch in 2016, Huff was cut heading into 2017. He worked out for the Saints on two occasions during the season.
Undrafted in 2014, Elliott spent three seasons with the Packers before joining the Cowboys in 2017. He has posted four sacks and an interception in 39 career games.
