SANTA CLARA, Calif. (AP) -Circumstance and personnel are leading the struggling San Francisco 49ers to change course in their offensive approach.

Proclaiming to be a power-rushing team from the start this season, the 49ers could be going airborne more often now that quarterback Alex Smith and rookie wide receiver Michael Crabtree have joined the huddle.

Offensive coordinator Jimmy Raye said Thursday that the 49ers won't change their philosophy despite a two-game losing streak and an offense that ranks 29th in the NFL.

But the team will adjust its attack and game plan to better take advantage of its passing weapons.
