There were some rumblings that a deal may have already been hatched between the two sides, but that isn't the case. At least not yet, according to ESPN's Adam Caplan:
No deal with Spikes and the #Bills, source said. Story is not true.— Adam Caplan (@caplannfl) March 14, 2014
Doesn't mean the Bills won't get a deal done with him--just nothing even close at this point.— Adam Caplan (@caplannfl) March 14, 2014
For now, Spikes is still in Orchard Park visiting with the coaching staff and front office of the Bills.
Keep checking back for any new updates on the situation.
