Kansas City waived Thompson on Monday, Sam McDowell of The Kansas City Star reports.
Thompson failed to reach the 4.0 YPC mark in either of his two seasons with the Chiefs, across which span he logged a total of 26 regular-season appearances. With Jerick McKinnon and Darrel Williams (head) around to provide depth behind Clyde Edwards-Helaire (ankle), and Derrick Gore having put together a solid preseason, Thompson's spot on the roster was rendered superfluous. The third-year pro will look for another opportunity elsewhere in the league.
