Browns RB Montario Hardesty has been diagnosed with a dislocated thumb, and will sit out of Thursday's preseason game. Hardesty is still practicing on a limited basis, but this might just about do it for his roster chances. The Cleveland Plain Dealer reported last week that Hardesty had a "decent chance" of keeping his roster spot, but only if he stayed healthy. Thus far in camp, he's been unable to stay healthy, while Dion Lewis has showed well. We might not know Trent Richardson's primary handcuff until after the third preseason game. Brandon Jackson is also in the mix.
