The new touchdown king of the NFL quarterbacks isn't getting much time to savor his record-breaking night, as Peyton Manning and the Denver Broncos face a quick turnaround and a key division clash against the visiting San Diego Chargers on Thursday. The Broncos are aiming for their fourth straight win after Manning passed for 318 yards and four TDs in a 42-17 win over San Francisco on Sunday night. Denver has a half-game cushion in the AFC West over San Diego.
