Denver cut Arrington after failed physical

Posted by ESPN.com's Bill Williamson

The Broncos' difficult offseason with running back J.J. Arrington came to a head Wednesday when the team released him.

Arrington, signed to be a third-down back in Denver, was released because he failed a physical. He had a knee injury he suffered with Arizona. He was recovering from the injury when Denver signed him earlier this offseason. Apparently, he was cut after he could not participate in a passing camp this week.

Arrington's time in Denver was ill fated. He was signed on the first day of free agency but the deal was voided by the league because of contractual issues. Arrington eventually signed a four year, $10 million deal with Denver. He received a $100,000 signing bonus and a $1.7 million roster bonus. He could conceivably sign back with Denver when his knee problem heals.

Denver certainly doesn't have a shortage of running backs. It drafted Knowshon Moreno with the No. 12 overall pick. New Denver coach Josh McDaniels has said Moreno has potential to be a three-down back. The team also signed veterans LaMont Jordan and Correll Buckhalter during free agency. The team also has holdovers Ryan Torain and Peyton Hillis
