Keller has been dealing with knee injuries but if he is healthy now he could provide a nice bit of insurance for the Patriots who currently have Rb Gronkowski working his way back from a torn ACL.
Just eight months ago Keller suffered a knee injury that saw him tear three ligaments and suffer a dislocation.
Dolphins free-agent TE Dustin Keller is visiting the Patriots today, per source.
