FLORHAM PARK, N.J. (AP) -- The New York Jets hope C.J. Spiller can help boost their backfield with some speed and versatility.
The veteran running back was officially signed Wednesday, and the Jets waived running back Knile Davis a day after claiming him off waivers.
Spiller joins a Jets backfield that includes Matt Forte and Bilal Powell, and he's reunited with offensive coordinator Chan Gailey, who coached Spiller during some of his best seasons in Buffalo.
''Obviously, he's played in the offense,'' coach Todd Bowles said.
