Humber, 29, originally signed on with the Colts as an undrafted free agent out of North Dakota State back in 2009. He lasted just over a year in Indianapolis before signing on with the Saints during the 2012 season.
Humber was in the final year of his two-year, $2.085 million contract when he was cut loose back in February. The Patriots later signed him to a contract, but elected to cut him loose on Tuesday to get down to 75 players.
In 2015, Humber appeared in 14 games for the Saints and recorded 47 tackles, one sack, and a pass defense.
