Austin, a 31-year-old who signed for $2.3 million back in March, had just one reception for 12 yards in his last four games.
While this could be an example of Kelly simply preferring youthful energy in the lineup, it is interesting that the move is coming after a statement victory in which Kelly tinkered with the lineup. He also admitted to running the football more in order to aid his winded defense.
Austin also gets the rest of his money because he is a vested veteran.
Austin was seen as a high-priced flier for Kelly, especially after he went on injured reserve in 2014 with a kidney issue as a member of the Browns. Austin spent the previous eight seasons in Dallas.
UPDATE: Austin cleared waivers Wednesday to become a free agent, NFL Media Insider Ian Rapoport reported.
