Cleveland Browns running back Trent Richardson has no plans to miss Sunday's game against San Diego. Coach Pat Shurmur said the rookie, who has damaged cartilage in his ribs, practiced Thursday and looked better than he did last week. "He did a lot of work and you just do as much as you can to get them as good and as ready as they can be for 1 o'clock Sunday," Shurmur said. Richardson vowed that he would be on the field Sunday and shunned the idea that he would stay on the sideline until the Browns' Nov. 11 bye week, according to The Plain Dealer. "They already know what my mind-set is," Richardson said. "I'm not gonna sit down. That's just never been in me to sit down. I'm going to go out there and see what I can do." Richardson, who missed most of training camp and the preseason after arthroscopic knee surgery, has rushed for 348 yards this season.
