Spikes visited the Patriots on Wednesday, csnne.com reports. Spikes, who played with the Patriots from 2010-13, spent the 2014 season with Buffalo, recording 54 tackles for the Bills in the process. While the Patriots have more pressing needs on defense than linebacker, bringing back Spikes would bolster a unit at the position (particularly against the run) that also includes Jerod Mayo, Jamie Collins and Dont'a Hightower.
