Christian McCaffrey is expected to make his San Francisco 49ers debut Sunday against the Kansas City Chiefs, sources told ESPN's Adam Schefter.

McCaffrey's availability comes just three days after the 49ers and Carolina Panthers agreed to a blockbuster trade for the star running back and just two days after he flew to San Francisco and joined his new employer.

The 49ers have a package of plays in Sunday's game plan for McCaffrey, who has picked up what he could of the offense quickly, sources told Schefter.
