Browns running back Trent Richardson continued to sit out organized team activities today, but he downplayed the significance of the strained muscle in his right shin.

“It ain’t no biggie,” Richardson said. “It’s not nothing to worry about. I could be out there, but they want to be cautious about it and make sure I’m healthy.”

Richardson said he doesn’t know whether he’ll participate in the team’s mandatory minicamp June 4-6. Coach Rob Chudzinski said he hasn’t made a final decision, though the team will be conservative this time of year with Richardson.

“We’re going to be cautious about it,” Chudzinski said. “But we’ll see early next week.”

Richardson said he’s ready to return, even though Chudzinski sounded as if he’ll choose to play it safe.

“If they let me go, I’m going to go,” said Richardson, the third overall pick in last year’s draft. “It’s going to be day-to-day. If they tell me to suit up tomorrow, I’m going to be out here working tomorrow. So I’m letting coach make the decision, and I’m happy with his decision. I know he’s going to do the best thing for me, and I know he’s going to do the best thing for the team.”

Richardson said he suffered the injury while running during a practice. He also sat out last Thursday.

Richardson said an MRI wasn’t even necessary for his injury.

“It was nothing that serious to even be looking at it that far,” Richardson said. “[The team’s medical personnel] just felt around on it, and they were just like, ‘We’re going to sit you out for right now ‘cause we don’t want nothing to happen to you as far as not being able to play in the season.’”

Richardson battled injuries throughout his rookie season last year. He underwent surgery Aug. 9 to remove a piece of loose cartilage from his left knee, which he also had scoped about six months earlier. He returned in time for the regular-season opener Sept. 9, even though he missed most of training camp and all four preseason games.

Then in Week 6, Richardson suffered two or three broken ribs against the Cincinnati Bengals. He played through the injury before being sidelined in the regular-season finale with a left high ankle sprain he suffered in Week 16 against the Denver Broncos.

“It’s not going to be like last year, being hurt,” Richardson said. “Injury-prone is not going to be me.”

Richardson’s teammates certainly hope he’s right.

“We need Trent back, and that’s why him taking some time off now and getting 100 percent is I think a good idea,” quarterback Brandon Weeden said. “I told him the same thing. I said, ‘We need you in training camp and ready for Week 1.’ He’s going to make this offense better. Yeah, we talk about all the balls being thrown downfield and doing all those things, but you’ve got to hand it to [No.] 33. He’s too vital for this offense to be good, be productive. So we need him back ASAP.”

Richardson did light exercises on the sidelines during practice. He insisted his injury isn’t preventing him from learning the new offense installed by Chudzinski and offensive coordinator Norv Turner.
