The Buffalo Bills have signed 323-pound Stefan Charles off the Tennessee Titans' practice squad and onto their 53-man roster.
The 6-foot-5 Charles entered the NFL as an undrafted rookie this spring. He's a native of Oshawa, Ont., and played college football in Canada with the University of Regina. In 22 career games with Regina, he had 19.5 tackles for loss and 9.5 sacks.
He missed most of his fourth college season due to a hand injury. He was the No. 2 ranked Canadian prospect entering the 2013 Canadian Football League draft and was picked 10th overall. He's 25.
