The Chicago Bears finalized their draft class on Tuesday by signing the rookie Sam Roush, a late pick. The move is part of earlier signings announced by the club. A defensive star will head to the Sack Summit later this week to discuss pressure tactics with peers. In a different incident, a family dog jumped between a charging bear and a young boy in a wooded area, preventing injury. Wildlife officials said the bear was released unharmed. Meanwhile, rescued moon bears from an illegal farm were relocated to a sanctuary where they stepped on grass for the first time, authorities said.
