With an efficient offense led by Carson Palmer, an opportunistic defense that stepped up in the final minutes and a clutch kick by Sebastian Janikowski, the Oakland Raiders turned a somber mood into a celebratory one. Janikowski kicked a 43-yard field goal on the last play as the Raiders scored the final 13 points after wide receiver Darrius Heyward-Bey was knocked out and hospitalized by a scary hit to beat the Pittsburgh Steelers 34-31 on Sunday.
