Browns linebacker D'Qwell Jackson is looking forward to playing in a 4-3 defense for the first time in his professional career. He's also excited about returning from his second torn pectoral muscle.
Jackson said he played in a 4-3/3-4 hybrid defense during his college days at the University of Maryland. He said he expects to play middle linebacker in Browns defensive coordinator Dick Jauron's 4-3 system.
"I gotta know every (linebacker) position," Jackson said. "Right now, they're saying (I'll play) Mike backer. But I also have to learn the Will. I also have to learn the Sam because you never know in this business. I'm a proven example of it -- injuries are gonna happen -- so you have to have a guy that you can fill in and not miss a beat."
Jackson, who has missed the Browns' past 26 games because of the aforementioned pectoral injuries, said he has been cleared to fully participate in practice. The Browns start training camp Friday. Their first practice in pads is scheduled for Monday, coach Pat Shurmur said.
"Coming off two pectoral years, my approach this (offseason) was totally different, mainly focusing on overall health," Jackson said. "Not just training for football, but training for overall health -- from family history to just a new appreciation for my body. ... My training this year was more focused on (my) core, focusing on lengthening my muscles, making sure my massages were there, seeing the chiropractor, just fine-tuning the things that I'd been doing in previous years. But this year, I feel great. I feel in great condition. My body feels great. When I go out there, I'll train to the point to where I don't feel like I was second guessing myself at all."
