Steward, 23, was taken in the sixth round of last year’s NFL draft by the Bills. He managed to make the 53-man roster coming out of the preseason, but he was placed on waivers earlier in the week.
Steward was in the second year of his four-year, $2,403,828 rookie contract at the time of his release.
In 2015, Steward appeared in seven games for the Bills and recorded two tackles. Buffalo later placed Steward on season-ending injured reserve with a back injury.
Yount, 27, originally signed on with the Buccaneers as an undrafted free agent out of UCLA back in 2011. He spent just a few months in Tampa Bay before he was waived midseason and later signed by the Browns.
Cleveland eventually signed him to a five-year deal in 2013 only to cut him loose a few weeks after last year’s draft.
In 2014, Young appeared in all 16 games for the Browns and recorded four tackles on special teams.
