The early prognosis on the Browns linebacker D'Qwell Jackson is that he could be back in 4-8 weeks from his right pectoral injury, but he'll get a second opinion from his New York surgeon, a league source told The Plain Dealer. If Jackson returns in four weeks, it's conceivable he could be back in time for the opener Sept. 12 at Tampa Bay. If it's eight weeks, it would be closer to the Oct. 10 game against the Falcons. But Jackson will proceed cautiously until he hears back from his surgeon, Dr. Frank Cordasco of The Hospital for Special Surgery in New York, the source said. He's hoping to know more by Thursday.
