Jarrett Stidham threw two TD passes following a lackluster performance from Bo Nix and Denver's starters, and the Broncos beat the San Francisco 49ers 30-9 in the preseason opener Saturday night.

The TD pass was Mahomes' only completion of the game, ending a brief, effective outing. Backup Gardner Minshew took over on the next series and ran for a 2-yard touchdown in the second quarter.
