The Buffalo Bills welcomed visitors Brandon Spikes and Anthony Dixon to the team's facility on Friday.
Spikes was a four-year starter with the Patriots, but ended his tenure there with a controversial decision to place him on season-ending injured reserve.
Dixon has been with the 49ers but has mostly been a spot player. He'd be in the mix as a third running back behind C.J. Spiller and Fred Jackson if he accepted any offer.
