The Tennessee Titans have placed fullback Quinn Johnson on injured reserve and replaced the veteran by promoting Collin Mooney from the practice squad.
The Titans announced the moves Saturday before heading to Pittsburgh for their season opener.
Johnson practiced Wednesday, but a quadriceps injury kept him out Thursday and Friday. The Titans worked out fullbacks Michael Robinson and John Conner on Friday but decided to promote Mooney.
The fullback played at West Point before serving three years with the U.S. Army. He spent most of last season on the practice squad before being signed to the roster late in the season and playing in two games.
