Buffalo Bills' running back James Cook did not take part in practice on Sunday. After practice, he gave a one-word answer for why he didn't take part.

The two-time Pro Bowler worked out on a stationary bike as his teammates went through drills. This is set against the backdrop of Cook wanting a new contract as he enters the final year of his rookie deal. He said little of his decision not to practice, but the subtext seemed pretty clear: The Bills, for their part, declined to comment.

Buffalo Bills running back James Cook was the one Buffalo star in line for an extension that didn't receive one this spring. Greg Rousseau, Khalil Shakir, Terrel Bernard, Khalil Shakir, and Josh Allen all received new deals over the offseason, but the Pro Bowl running back was left without one.
