Spiller, 29, is a former first-round pick of the Bills back in in 2010. He spent five years in Buffalo before signing a four-year, $16 million contract that included $9 million guaranteed with the Saints in 2015.
Spiller was set to make a base salary of $1.7 million for the 2016 season when the Saints cut him loose a few weeks into the regular. The Seahawks signed him to a contract a few weeks later but he lasted just a month in Seattle.
The Jets gave Spiller another shot in November of last year, but they too cut him loose after a month.
The Chiefs signed Spiller to a contract this offseason but elected to release him as they trimmed down to the 53-man limit. He has been on and off of their roster ever since.
In 2017, Spiller has appeared in one game and rushed for two years on one carry.
