The Kansas City Chiefs released four players from their roster on Thursday.
The Chiefs terminated the contract of center Bryan Mattison and placed fullback Patrick DiMarco, linebacker Cory Greenwood and quarterback Alex Tanney on waivers.
Greenwood saw the most playing time during his time with the Chiefs though it was primarily on special teams. He appeared in all 48 games over the last three seasons for Kansas City.
DiMarco started four games at the fullback position and Mattison appeared in four games for Kansas City as well. Tanney spent last season on injured reserve after injuring a finger late in training camp.
