ALLEN PARK, Mich. (AP) - Calvin Johnson is trying to stay positive after Nate Burleson's injury. Burleson was coming off a big game last weekend at Washington, but he broke his arm in a car crash early Tuesday, so now the Lions will have to rely on Johnson and a number of less proven options at wide receiver. That didn't work out well last season, when Burleson hurt his leg and the Lions slumped to a 4-12 finish. Johnson doesn't sound too worried about a repeat. In fact, he's hopeful some of his teammates will benefit from bigger roles. Burleson's absence toward the end of last season didn't hurt Johnson's stats. He finished with 122 catches for a record 1,964 yards - but Detroit's offense could have used more balance. Sunday the Lions host the Bears at Ford Field with kick off at 1 p.m.
