SANTA CLARA, Calif. (AP) — Trey Lance threw an 80-yard touchdown pass that led to loud cheers from San Francisco fans and also showed some rookie traits in his preseason debut in the 49ers' 19-16 loss to the Kansas City Chiefs.
Lance had an up-and-down first performance with a few off-target throws, three sharp passes that were dropped by his receivers and four sacks behind a spotty offensive line.
Chad Henne threw a TD pass to Byron Pringle after a short cameo by Patrick Mahomes to begin the game and rookie Shane Buechele scored on a 1-yard keeper with 1:14 to play to win it for Kansas City.
