The Broncos are releasing defensive lineman Ahtyba Rubin, a source tells Mike Klis of 9News (Twitter link). In a related move, offensive lineman Billy Turner has been placed on injured reserve. 
Rubin was cut by the Seahawks in early September, making him a free agent in the midst of what was supposed to be a lucrative three-year deal. He signed with the Broncos roughly two weeks later. After dressing just two times in one month, the Broncos are putting him back on the curb.
Klis (Twitter link) expects the Broncos to use their newly-open roster space to add some depth at wide receiver. The Broncos have only three healthy wide receivers available heading into Sunday’s game against the Chargers. Some veteran help would be welcome behind top target Demaryius Thomas as Emmanuel Sanders and Isaiah McKenzie deal with injury.
