DENVER -

The Super Bowl teams slogged through a preseason opener delayed by lightning and a flurry of flags Thursday night before linebacker Steven Jackson's end zone interception of Terrelle Pryor's pass sealed the Denver Broncos' 21-16 win over the Seattle Seahawks.
    
In between a 46-minute delay, both starting offenses put together long touchdown drives that ate up more than 9 minutes and were kept alive by a wave of yellow flags.
    
Altogether, there were 25 accepted penalties, 13 on Seattle and a dozen on Denver.
    
Ronnie Hillman's 1-yard TD run capped Denver's 14-play, 61-yard drive in which Peyton Manning completed 9 of 11 passes for 63 yards and the officials threw six flags, including one for offsetting penalties.
