Tony Sparano staying with Raiders

ALAMEDA, Calif. -- Tony Sparano has signed a two-year contract to remain the assistant head coach/offensive line coach of the Oakland Raiders, the team announced Friday.

The move comes after Sparano had been mentioned as a candidate to join new coach Lovie Smith's staff with the Tampa Bay Buccaneers.

Heading into the week, only offensive coordinator Greg Olson and linebackers coach Bob Sanders had contracts for 2014 among coach Dennis Allen's assistants. At least three other coaches on Tuesday agreed to one-year extensions, with Allen having two years remaining on his contract.

There had been a potential snag as owner Mark Davis was leaning toward one-year deals for coaches with expiring contracts. But with Sparano getting two years, his contract length and job security is now the same as Allen's. The move also ensures continuity with the offensive line.
