A finalist for the Raiders' permanent job after guiding the team to a 3-9 record as Dennis Allen's replacement, Sparano was passed over in favor of Jack Del Rio last week.
Although Sparano's background is in offensive lines and coordinating a rushing attack, he was Bill Parcells' tight ends coach with the Dallas Cowboys for two years. General manager Trent Baalke also worked under Parcells as personnel scout with the New York Jets from 1998-2000.
Sparano is replacing Eric Mangini, yet another member of the Parcells coaching tree, who just interviewed for new 49ers coach Jim Tomsula's vacant defensive coordinator position.
Provided Vernon Davis is still on the roster with a scheduled $4.7 million salary, Sparano will be charged with coaxing a bounce-back season out of the two-time Pro Bowl selection.
