The agreement, first reported by the NFL Network's Michael Lombardi, came more than a week into the free-agent signing period and included an "ironing-out" session with coach Jim Harbaugh after Peyton Manning spurned the 49ers on Monday to sign with the Denver Broncos. But, in the end, Smith is back with the 49ers -- just as everyone around the NFL thought would happen all along.
Smith's return to the 49ers had its share of drama, though. Harbaugh and offensive coordinator Greg Roman secretly traveled to Duke University in Durham, N.C., on March 13 to watch Manning throw.
