Browns rookie running back Montario Hardesty tore his ACL on Thursday night against the Bears and will miss the entire 2010 season, according to a source. Hardesty was Cleveland's second-round pick in April's NFL Draft. "I hurt my knee making a cut," Hardesty said immediately following the game. "I really don't know what it is. I can't say it's not frustrating. I want to stay positive, get as much information as possible and return my focus to getting better. I'm hopeful whatever it is, I can get back as soon as possible."
