Spiller, who was recently released by the New Orleans Saints, played 13 games last season, but was inactive in week 1 this year. He was shocked by his release from New Orleans so early in the season, but the 29-year-old was confident that he would find a new home sooner rather than later.
The running back spent the first five seasons of his career with the Buffalo Bills, and has averaged 4.9 yards on 704 carries in the NFL. He has also recorded 192 catches for 1,434 yards. With the Saints last season, Spiller had 112 yards on 36 carries, as well as 239 yards on 34 catches.
He is hoping to rejuvenate his career with a team that has seen plenty of postseason success over the past few years. The veteran is expected to be the Seahawks' third-down back, and he is sure to make the most of any opportunity that Seattle will give him.
