James Robinson wasn't happy after being a healthy scratch for the New York Jets on Sunday.

The Jets acquired Robinson from the Jacksonville Jaguars in a trade on Oct. 24.

"Obviously, I didn't come here not to play," Robinson said. "Obviously, they brought me here for a reason. I don't expect anything unless I work for it, and I've been working my ass off. Me not playing pisses me off."

Robert Saleh replaced Robinson with rookie Zonovan Knight, who recorded 103 yards from scrimmage in his debut -- a 31-10 win over the Chicago Bears.

Robinson said he was informed last Wednesday by running backs coach Taylor Embree that he would be inactive against the Bears.

"Obviously, I was upset about it," he said. "I don't know what they have planned for me."
