The Bills already have Kansas City's first-round pick in the 2018 National Football League draft after their trade this past April.
Ragland was a second-round pick in 2016 and missed all of his rookie season with a torn ACL.
Drafted by the Bills in the second round of the 2016 National Football League draft, Ragland looked to be a good fit in the club's previous 3-4 defensive scheme.
Ragland had seen decreasing playing time at middle linebacker in the preseason.

This prompted the authorities to exhume other bodies, which led to the revelations of many other deaths due to drug overdose. Hundreds of medical records have been analysed, with 134 bodies being exhumed to test samples for drug residue.
The Buffalo Bills continue to clean house, making their fourth major trade of the preseason.
Ragland looks to be a good fit for the Chiefs' 3-4 defensive scheme, which is very similar to the system the linebacker was trying to learn as a rookie past year.
To create a roster space for Ragland, the Chiefs released linebacker Josh Mauga on Monday.
Ragland, an All-American linebacker in 2015 for Nick Saban's Crimson Tide, won national titles as a freshman in 2012 and as a senior in 2015.
A healthy Ragland would be an incredible upgrade for Kansas City going forward, practically giving them an extra first round pick.
