Shane Ray, who hasn’t played in an NFL game since December 2018, posted Sunday on Instagram that he has signed with the Buffalo Bills.The defensive end/linebacker was selected in the first round (23rd overall) by the Denver Broncos in the 2015 NFL Draft out of Missouri. After four seasons, he signed with the Baltimore Ravens as a free agent but was waived before the 2019 regular season.After playing the past two years with the Toronto Argonauts of the Canadian Football League, Ray, who turns 30 on Thursday, participated in the Bills’ rookie minicamp this weekend.Bills general manager Brandon Beane said in an article Friday on the team website that free agents such as Ray were invited to the tryout because some positions have open spots.”We didn’t hit on any D-ends after the draft as far as guys to sign, and so that’s why we were excited to get the kid Cameron Kline last week that we claimed from Indy,” Beane said. “We probably at some point may look to add a D-end between now and start of camp. And so instead of doing a workout, here’s a guy out there, let’s bring him in here for a couple of days, test his knowledge, test the skill set, see where he’s at.”
