With NFL training camps set to begin, the Detroit Lions made their final few roster moves to make their 91-man roster ready for the start of practice. One of the new additions signed to the roster was defensive back Tyson Russell, who went undrafted after playing collegiately at Vanderbilt. Russell has already shown his mettle to the Lions, with the Commodore trying out with Detroit following the NFL Draft. One of the biggest strengths of Russell is that he played some of the toughest competition, that being SEC football.
