Browns running back Trent Richardson insists he’s 100 percent healthy and wants to play Thursday night in the second preseason game of the year against the Detroit Lions but he also is keeping the big picture in mind. The organization’s No. 1 goal for Richardson is to ensure he’s ready to roll Sept. 8 when the Miami Dolphins come to town for the regular-season opener. Browns coach Rob Chudzinski said he hasn’t decided yet whether Richardson will face the Lions after sitting out the exhibition opener last week against the St. Louis Rams. Richardson rested for two practices Aug. 2-3 after being kicked in the right shin the same one in which he suffered a strained muscle in the spring. He returned to action Aug. 5 but was limited in team drills. On Sunday he received more reps in 11-on-11 sessions and looked sharp running the ball as his workload increased. “The ultimate goal is to make it to Miami but it’s one day at a time” Richardson told the Beacon Journal after practice Sunday. “You don’t want to do nothing too crazy to get hurt. At the same time you want to be on time with everything with your timing the game conditioning and everything like that. Coach [Chudzinski] lets me take my reps in practice here and there and we’re just seeing how everything goes through with my shin. “I wanted to be out there [in the preseason opener]. Coach makes the decisions. They just told me they were going to sit me down and that was that. There were no words other than that. Coach made a decision and it happened like that.” Speaking of that troublesome shin Richardson said it feels fine. “Oh yeah 100 percent ready to go and Coach will let time heal and let time do what it does” said Richardson the third overall pick in last year’s draft. “I’m with Coach and letting him tell me what to do.” Last year Richardson missed most of training camp and all four preseason games after he had a piece of loose cartilage surgically removed from his left knee Aug. 9. He still made it back in time for the regular-season opener against the Philadelphia Eagles and played most of the year with two or three broken ribs suffered in Week 6. Still some believe Richardson could benefit from his first taste of the preseason.
