The Bills executed a roster move they likely did not anticipate Thursday. Veteran LB Keenan Robinson has chosen to retire.

A former fourth-round pick by Washington in 2012, Robinson played five seasons in the NFL, chiefly for Washington and the New York Giants. Just 29-years old, the Bills placed the linebacker on the reserve/retired list.

Robinson found it difficult to move up Buffalo's depth chart at the linebacker position. He was largely relegated to second and third team reps through the course of training camp, after signing with the Bills just before training camp opened in late July.
