Chris Chester - Washington starting RG released

Link: http://profootballtalk.nbcsports.com/2015/05/27/report-washington-releasing-chris-chester/ Washington is parting ways with its starting right guard.The club will release Chris Chester, ESPN’s Adam Caplan reported Wednesday.He's 32 and might be worth picking up for competition for Marpit at RG. Also could be depth if none of the others on the roster can push by him. Since he's a release, I assume he has to go through waivers - right?
