Richardson addressed reporters Wednesday at Browns minicamp, claiming that a recent report from ESPN Radio in Cleveland has overstated the severity of his shin injury.
Browns coach Rob Chudzinski announced Tuesday that Richardson would miss this week's three-day minicamp "strictly as a precaution" but emphasized that the second-year star should be ready for training camp on July 26.
Richardson echoed those sentiments Wednesday, saying his injury is "nothing that big to worry about."
"I still expect to be out there Day 1 [of training camp]," Richardson said, according to the Akron Beacon Journal. "People are saying I've got another injury, and it's farther than what people are saying it is. And no, it's not.
"Coach got me out for precautionary reasons. It's nothing that big to worry about."
Richardson also addressed ESPN Radio in Cleveland's report that he has been taking migraine medication which has caused him to scale down his weightlifting sessions and lose body weight as a result.
"I've been taking migraine medicine my whole life, like a normal person would do if they had migraines," he said, according to the Beacon Journal. "As far as not lifting, I lift just like everybody. I just got done lifting yesterday. I can outlift anybody in the weight room."
Richardson, the third overall draft pick in 2012 out of Alabama, sat out Cleveland's final set of organized team activities last week with the shin injury. At the time, he vowed, "Injury-prone is not going to be me."
The Browns did not permit Richardson to speak with the media after practice Tuesday. The 5-foot-9, 230-pound back walked off the field without a limp and did not acknowledge the reporters following him.
Chudzinski, though, did his best to downplay the severity of Richardson's injury, which occurred in early May while running at Cleveland's team headquarters.
"I don't know the medical (risks going forward), but he's got a strain right now," the first-year coach said Tuesday. "I'm not concerned about anything else at this stage.
"My only concern, really, is Trent needing to stay into it mentally while he's out. So far, he's done a great job taking mental reps and getting into game shape."
