The Broncos are set to sign outside linebacker Dondrea Tillman to a three-year deal with a $10,000 signing bonus. Tillman, 26, played for the Birmingham Stallions in the United Football League, showcasing his skills with 92 tackles and 8.5 sacks in the past three seasons. He will bolster a linebacker room that includes other notable players. The team will need to make roster adjustments due to Drew Sanders' injury sidelining him for the start of the season.
