Browns linebacker D'Qwell Jackson, who sat out the last 10 games of last season with a torn pectoral muscle, left practice Thursday with tightness in the other injured pec and will shut it down at least until next Wednesday.
CLEVELAND -- Browns linebacker D'Qwell Jackson experienced tightness and fatigue in his partially-torn pectoral muscle Thursday and will be out of action again until at least next week.
Jackson, who first suffered the injury Aug. 10, quit practicing Thursday after he felt something in the pec and sat out again on Friday. He'll miss Sunday's game in Baltimore and will try to hit the field again next Wednesday.
"If I go out there, I don't want to feel anything,'' said Jackson. "At this point, it was too early. It was best I stayed in today and try to shoot for next week.''
Jackson said it wasn't one particular play that set it off. "I knew it was going to happen (feeling tightness),'' he said. "But it was a little frustrating. I felt like I could've finished it out, but I want to make sure everything is 100% ready to go when I do step out there on Sunday.''
Jackson began practicing on Wednesday and said he felt fine heading into Thursday's session.
