Lions sign Stefan Charles to a one-year deal

The Lions continued to make depth move in the middle of the night on Thursday. In what is now the fourth signing on the second day of NFL free agency, Detroit signed defensive tackle Stefan Charles, formerly of the Buffalo Bills.

Per NFL Network's Ian Rapoport:

#Bills DT Stefan Charles, non-tendered, is signing a 1-year deal with the #Lions, source said.

Stefan Charles was previously a restricted free agent with the Buffalo organization; however, he was one of three RFAs that the Bills did not tender contracts to and thus became an unrestricted free agent.

Charles is a Canadian-born football player from Ontario. He played college ball with the University of Regina Rams of the CIS. Although he was selected tenth overall in the 2013 CFL draft, he garnered interest from several NFL teams and signed an undrafted free agent deal with the Tennessee Titans. The Bills signed Charles from the Titans practice squad in 2013. Charles started one game for the Bills in 2015 and had 5.0 sacks for them over his three seasons in Buffalo.

The move is another depth signing for the Lions. With Haloti Ngata and Tyrunn Walker both returning next year Charles can expect to find part-time playing time, depending on his performance during training camp and preseason.
