JEFFERSON — With a 31-16 lead during the fourth quarter, the Jefferson Dragons didn’t imagine that it would take three overtimes to advance to the state semifinals. But the Dragons (12-1) needed that much extra time to defeat the Fitzgerald Purple Hurricanes 53-51 Friday night in Jefferson. Jefferson advanced behind the arm of quarterback Bryant Shirreffs, who found Tristen Jackson on a 5-yard touchdown pass to tie the game at 51-51 in the third overtime.
