ENGLEWOOD, Colo. — There were an NFL-record 13 individual 300-yard passing performances last weekend.

Surprisingly, Philip Rivers and Kyle Orton, weren't among them.

Rivers, who leads the NFL with 2,944 yards passing, had the weekend off as the San Diego Chargers were on a bye. Orton, who's second with 2,806 yards, came up four yards shy of his sixth 300-yard game this season in Denver's blowout of the Kansas City Chiefs.

The two quarterbacks who are on pace to challenge Dan Marino's single-season record of 5,084 yards set in 1984 meet in San Diego on Monday night in what promises to be another aerial show.
