ORCHARD PARK, N.Y. – The confidence C.J. Spiller has in his abilities remains high, even though the Buffalo Bills running back's playing time and production are suddenly diminishing.

Spiller says he's not worried in the least.

The numbers, however, indicate differently. They raise questions over the 2010 first-round draft pick's role in the offense, and whether his days in Buffalo are running out once his contract expires after this season.

Spiller is coming off one of his least productive games. He had six carries for 19 yards, lost a fumble and played just 12 of 69 offensive snaps in a 37-22 loss to New England last weekend.

Coach Doug Marrone insists he's not lost faith in Spiller, but adds that doesn't mean the player can't be better.

Buffalo (3-3) hosts Minnesota (2-4) on Sunday.
