Fred Taylor rushed for 84 yards as the Jaguars controlled the clock for nearly 39 minutes while shutting down the league's top tailback and its most prolific offense.
After piling up 911 yards in their first two games, Denver managed just 265 versus the Jags. Henry ran just 11 times for 35 yards.
The Broncos had no choice but to go to the air in the fourth quarter, and Sammy Knight sealed the win with his first interception for Jacksonville in the closing minutes.
Both teams are 2-and-1.
