Broncos released/failed physical RB J.J. Arrington. Ouch, they're eating a $1.8 million signing bonus, and Arrington never even got in a practice for the team. Denver signed Arrington in March.
I heard they cut him because he needs knee surgery. Denver had an out for the knee and used it because they had enough RB's, there was not reason to waste a roster spot on a guy who wasn't going to be a contributer now.
