Input (English): Passage: Coming off their bye week, the Cardinals flew to Bank of America Stadium for a Week 8 duel with the Carolina Panthers. In the first quarter, the Cardinals took flight as kicker Neil Rackers got a 21-yard field goal. In the second quarter, Arizona increased its lead as QB Kurt Warner completed a five-yard TD pass to WR Anquan Boldin. The Panthers closed out the half with kicker John Kasay getting a 23-yard field goal. In the third quarter, the Cardinals increased their lead as rookie RB Tim Hightower got a two-yard TD run. However, Carolina began to rally as RB DeAngelo Williams got a 15-yard TD run, while QB Jake Delhomme completed an 18-yard TD pass to WR Steve Smith. The Cardinals replied with Warner hooking up with Boldin again on a two-yard TD pass (with a failed PAT), but the Panthers took the lead on Delhomme's 65-yard TD pass to Smith. In the fourth quarter, Carolina pulled away as Kasay nailed a 50-yard field goal.
